CHARM2 FEATURES

These features are available in the full CD version. Some features
may not be available in the on-line abridged xls file.



Information listed:
-------------------

-names and cross-identifications
-VLTI observations
-object type
-wavelength and method of observation
-characteristic size (measured diameter, UD/LD, upper limit, shell, 
		      estimated diameter, binary parameters)
-comments
-coordinates (from simbad, proper motions and epoch)
-B,V,K,correlated K magnitude, 12 micron fluxes
-spectral type
-variability type, parallax, proper motion
-references
-angular distance from a given point in the sky
-visibility for a given lambda & baseline


Links provided for each source:
-------------------------------

-data directory structure, one directory per source
-full simbad files with measurements and references (offline)
-direct connection to Simbad (online)
-published and unpublished photometric data
-finding charts
-reference titles and original reference papers as PDF



Computations provided 
(mostly by buttons, scrollbars, etc.):
---------------------------------------------------
*in main worksheet
-active display of visibility for each source, updated with
 changing baseline and wavelength
-active display of distance from a reference point, updated with
 changing alfa,delta of reference point

*in Geo worksheet
-definition of time, date (presets for current day/time available)
-definition of baseline (presets for VLTI baselines available)
-definition of wavelength (presets for VINCI/AMBER/MIDI available)
-definition of observing place (preset for Paranal available)
-definition of source coordinates and diameter (with error)
 (direct link to all CHARM data, including diameters)

-computation of Julian Day, Local Sidereal Time, Hour Angle, Elevation,
                Airmass, Baseline Length, Baseline Position Angle.
-computation of visibility, visibility square (with errors), decrease
                of apparent magnitude (mag - corr_mag).
-plots of airmass, hour angle, baseline length and position angle, 
                visibility and visibility square as a function of time


*filtering, sorting, etc. as provided by Excel
