	- second sky subtraction disabled for large dsky, 14sep06
	- store more things in xmdv-object,		14sep06
	- new option /UNMASKED for xmdv::photometry(),	14sep06

	- Introduced Installation Wizard, 12sep06
	- Fixed and Fitted mask will reset mask-filename, 12sep06
	- "Plot Almost Everything" in GUI
	- Error message if user asks for photometry from window 2
	  although EWS-photometry was used.
	- button in the mask-GUI to use default EWS-Mask with MIA
	- default is to fit the mask
	- Function xmidispvisi::baseline to compute the mysterious
	  projected baseline
	- get wavelength calibration directly from the input files

MIA+EWS version 1.4
	16-Jun-2006

	- "Save xmdv-object" in GUI-menu
	- new function midifile_search
	- added baselines between AT-stations to calibrate_disk.pro
	- cleanup-routine has option /keep_compr
	- support for SCI_PHOT mode
	- adapted to new "single-file" EWS-Photometry
	- reactivated SCI_MODE by FP (under development)
	- improved determination of mask parameters
	- xmdv recognizes OBS_FRINGE_TRACK_DISPERSED as fringe track data
	  when called with one filename only
	- flux in SCI_PHOTometric channels is plottet in GUI
	- When xmdv determines whether a scan was on target or on sky, a
	  number of frames at the beginning and end of the scan is
	  ignored.  This number can be set with the parameter TARTYPSKIP
	- removed switch /DONT_WRITE
	- serious errors are logged in "ERRRORS/<MIDI-filename>.log"

MIA+EWS version 1.3
	14-Dec-2005

	- fixed bug in mask_utilities that caused xmdv to always use the
	  mask created from the fitted traces (this occured only with the
	  "old" photometry)
	- support for SCI_PHOT in photometric and interferometric files:
	  x->photometry(/Aphot) or /Bphot, x->sci_photometry(/A) or /B
	- get_photometry() replaced by photometry()
	- added small window to set plot-ranges from GUI
	- new routine print_results
	- new menu items in GUI: "Mask GUI", "White Fringe Method", and
	  "Save Visibility"
	- new routine save_visibility (writes IAU-format)
	- miamask uses Walter's oirChopPhotoImages
	- photometry from oirChopPhotoImages and oirMakePhotoSpectra
	  This breaks just about anything with SCI_PHOT mode.
	  We get only one spectrum per photometric file, therefore
	  get_photometry(/A2) and ...(/B2) return only zeroes.
	- added x->make_white_fringe to allow changing dispersedtrack and
	  number of bins on the fly
	- removed SKY- and THRESHOLD-options
	- removed MASKTHENMULTIPLY and MULTIPLYTHENMASK
	- get_photometry returns /AB by default
	- introduced x->set_(frame|opd|flux|fluxdiff|fringe_ampl)_range
	- Cached_MeanRMS recreates cache-file if it can't be loaded
	- renamed xmidispvisi::plot_disp_goodbad to xmidispvisi:
	  :raw_correlflux and added ability to estimate noise from same
	  scan as signal
	- xmidispvisi::calibratedvisi accepts an array of calibrators and
	  computes mean instrumental visibility
	- added option /SSN to x->raw_correlflux to estimate noise from
	  power in same scan as signal, but at different frequencies
	- added oirChopPhotoImages
	- force compilation in 32-bit mode (see makecfitsio)
	  This is tricky, since old gcc versions don't accept -m32, while
	  newer versions (those on 64-bit heaters) require it...
	- idl/cmps_form.pro: The IDL manual states that pickfile is
	  obsolete and should be replaced by dialog_pickfile.  Did that.


MIA+EWS version 1.2
	16-Jul-2005

	- compute TARTYP per scan, plot it over Flux Diff. (blue = S,
	  red = U), and select only scans on target for signal estimate
	- added PREFIX-option to xmdv
	- improved layout of plots in GUI
	- added CHARSIZE-option to x->gui
	- convinced IDL that short and long wavelength limits are floats
	  This affects the dispersed tracking algoritm so strongly I
	  wonder how it ever worked in the old version...
	- x->lambda() returns only valid datapoints
	- x->set_lambda_bins checks for out-of-range values
	- guesses scanlength if value in header is bogus
	- added parameter "errorlog" to xmdv et al.
	- print wavelength in plots of dispersed powerspectra
	- included the reducenight script by Frank and Thorsten
	- try to repair colortable after, e.g., atv has been used
	- get_photometry now uses lambda binning
	- changed selection of frequencies in power spectrum:
	  use always 4 pixels around mean frequency.  This is the
	  Right Thing to do as long as  scanlength << coherence length.
	- wavelength range returned by correlflux, visibility etc.
	  Now gives range from left edge of leftmost to right edge of
	  rightmost pixel.
	- changed xmidispvisi::get_trace to use miamask-object.  This
	  changes the syntax somewhat, read the friendly manual
	- reduced size of midigui to make it small enough for XGA displays
	- divide correlated flux by 2 so that visi = corrflux/photflux.
	  This cancels out with the factor 4 in the power determination

MIA+EWS version 1.1
	Intermediate release for Paranal observations in May 2005

	- new version of chop_nod_phot by Thorsten Ratzka:
	  Allows determination of the flux, position, and FWHM of the
	  source in each frame of the acquisition data
	- added tests for chopping throw zero, trace out-of-window,
	  and FWHM < 0
	- moved routines for mask creation etc. into object "miamask"
	- added procedure xmidispvisi::show_traces
	  Now you can plot or print the traces as often as you like
	- store traces in arrays in preparation for sci_phot mode
	- Mask check now plots pos/width of mask on top of RMS img
	- rewrote xmidispvisi::meanmask to use loops over tags to
	  simplify handling of HI_SENS and SCI_PHOT
	- new function make_mask_from_trace
	- removed warnings that this is an experimental version.
	  This does not make the results more reliable, though.
	- added some warnings about stupid parameter settings.
	- replaced "Bad threshold" by "Noise OPD" in GUI
	- fixed sqrt(2)-bug in display.
	- gui uses true- or pseudocolor depending on number of colors

MIA+EWS version 1.0
	3-Feb-05

	- added make_maskname in MIA/utilities.pro
	- improved file-type detection in xmdv,
	  now recognizes "*_CHOP" as photometric data

	  minrtsRef/config/prismmask_before_2003dec01.fits
	- added setup.csh for setup without IDL

	- fixed paths to C-programs in c/bin/disp* scripts
	- added README.MIA+EWS in cfitsio
	- added mia-script to simplify startup

MIA+EWS version 1.0-ESOtest
	28-Jan-05

	- added code to select predefined maskfile if the maskfile
	  generated from the photometry is not satisfying enough
	- removed assumption that maskfilenames are "PHOTOMETRY/Mask_*",
	  i.e. maskfiles can be specified with full path now

Version 1.06 (MIA+EWS version 1.0-MPIAtest)
	27-Jan-2005

	- incorporated changes by Frank Przygodda for Sci-Phot-mode
	  according to Walter, these won't work properly since they don't
	  do the mapping between photometric and interferometric channels
	  right.
	- threw in reducenight.pro and an extended version of
	  make_midi_log.pro

Version 1.05
	31-Oct-2004 (Halloween)

	- made white-light tracking the default again
	- removed install-light.sh, pure IDL-version does not work anyway
	- replace spawn,"rm" calls by file_delete
	- removed unused code
	- no longer uses environment variable vltiCbin
	- changed vltimake to _re_compile packages
	- simplified paths
	- the expert went away to search for his sunglasses

Version 1.04
	20-Oct-2004

	- made dispersedtrack the default, use /whitetrack to disable it
	- giving a directory to xmdv will start midiguis
	- xmdv will search for photometry if no photometry-files are given
	- fringe- and photometry-files can be given in any order
	- removed options that nobody remembered

	- fixed bug in Makefile that prevented compiling except on Solaris
	- set default noiseopd to 4mm
	- added code in xmdv to call midiGuis if argument is a directory,
	  and look for photometry if only fringe-track or -search is given


Version 1.03alpha5
	31-Aug-2004

	- added some interactive elements to 'chop_nod_phot'
          (orientation & assignment of the beams have to be verified)

Version 1.03alpha4
	19-Jul-2004

	- fixed bug that wrote traces_win[12].ps every time
	  now the files are created if SHOW_TRACES="ps" is given

Version 1.03alpha3

	- Thorsten changed some Makefile

Version 1.03alpha2
	7-Jun-2004

	Suggestions/Bug fixes by Ch. Hummel:
	- install.sh: "make clean" before "make"
	- miFitsTables: "make clean" rm's libraries
	- MIDIskySubImage cleans up imagedata-object
	- xmidispvisi ptr_free's good- and badfringes
	- missing expert in xmidimovie fixed

Version 1.03alpha1
	26-May-2004

	- fix stupid bug that selected the wrong pixels with Grism
	  (Versions 1.01 and 1.02 did not produce usable results with
	   Grism-data!!!)
	- added simple support for dispersed fringe-tracking:
	  The fringe amplitude is not computed in white light, but in a
	  number of wavelength-bins.  Activate it with:

	  x = xmdv(files,/dispersedtrack)
	  or
	  x = xmdv(files,dispersedtrack=20)

	  where 20 is the number of bins to use.  Default is 10, which
	  should be enough for all data we have so far.


Version 1.02

	- new, but still preliminary wavelength calib for Grism

Version 1.01
	29-Mar-2004
