Diameter solutions from VINCI -- April 2005 solution

NOTE:
These are the results from April 2005 as were contained in a poster presented at the VLTI conference. There are newer results obtained since these. See the index page for the latest results.

This is the list of diameter solutions as presented at the April 2005 VLTI conference in Garching. This was part of a poster presented there entitled
Diameter determinations from VINCI using global calibration solutions

Please read the caveats associated with these results.

Diameters in milli arc seconds, and rms errors
U = unresolved (maximum likelihood diameter solution shown, regardless)
I = Invalid (all numbers supplied directly by the algorithm, but meaningless in these, as well as a number of other unflagged cases)

Uniform Disk Diameter Solutions:
A few caveats:

These are not the final results! They are the raw output of the algorithm at its current stage of development.
A good number of the stars cannot be described by a single "diameter" (for instance, pulsating stars observed at a limited number of epochs, elliptical stars observed at a limited range of position angles, and stars with an undetected proper calibration) and the numbers reported are invalid. A few invalid results have been spotted and marked with an 'I'. But there are many more.
Many of the solutions smaller than 2 mas must be considered unresolved. The non-zero diameter printed is simply a maximum-likelihood solution, but a diameter of zero is not excluded with any degree of confidence. In these cases a 'U' has been supplied to indicate "unresolved."
The errors reported here are often too optimistic. That is because the algorithm currently does not take into account the correlation of calibration errors from observations conducted on the same night, which prevents reduction of these errors by averaging. A newer version of the algorithm will deal with this problem properly.
