This is version 2.0 of the catalog STARSFLUX (STellar Absolute Reference Spectroscopic Flux Library). The reference article (Gámez Rosas et. al 2026) has been submitted and is under revision.

See names_list_Dec30.txt for the list of stars included in the last version of the catalog. The names of the starts are based on the MDFC catalog edited to contain no spaces and no *s.


To select a good calibrator:
SearchCal is a tool developed to assist the astronomers in this calibrator selection process for long baseline interferometric observations. It can be used in: 
https://www.jmmc.fr/english/tools/proposal-preparation/search-cal/
A guide for selecting calibrators for MATISSE can be found in the SearchCal Wiki Page: 
http://www.jmmc.fr/twiki/bin/view/Jmmc/SearchCalHintsPage.
In the same webpage can be found a catalogue of bad calibrators: 
https://www.jmmc.fr/badcal/
We strongly recommend using the infrared excess ("IRflag") and calibrator ("CalFlag") flags displayed in the catalog of Cruzalebes et. al 2019 to identify good calibrators.
We remark that it is highly recommended that the calibrator's magnitudes match those of the science target.
