The Variable Stars ID is the same in this and all subsequent tables
The X and Y coordinate are relative to the 1995 October 30 epoch.
For each 800x800 pixels chip, pixel [1,1] is located at the edge of the pyramid.
RA and Declination are calculated using the IRAF task 
STSDAS.HST_CALIB.WFPC.METRIC, version 1.3.5 (July 1996).


Notes on the individual variable stars. 
V1: isolated, symmetric light curve, period too long to be determined, phase average
magnitudes are calculated for P=77 days. 
V2: very crowded region nearby, small amplitude.  Phase average magnitudes are calculated for
P=60.6 days.  
V3: at the edge of a very crowded group, several companions within five pixels.  Bimodal V light 
curve. Phase average magnitudes are calculated for P=46.3 days. 
V4: fainter companion 3 pixels away. Small amplitude, symmetric light curve; phase average
magnitudes are calculated for P=48.9 days.. 
V5: one magnitude fainter companion 2.4 pixels away; not variable from ALLFRAME photometry. 
V6: isolated, not found in DoPHOT photometry; magnitudes are derived from ALLFRAME photometry.  
V7: isolated, not found in the I photometry file. 
V8: three fainter companions 2.2 to 2.8 pixels away; not variable from ALLFRAME photometry. 
V9: two companions 2.8 pixels away, ~1 magnitude fainter; not in ALLFRAME photometry. 
V10: two magnitude fainter companion 2.1 pixels away; not variable from ALLFRAME photometry. 
V11: isolated; not in ALLFRAME photometry.  
V12: in a crowded region, even if no companions are identified within three pixels; not variable 
from ALLFRAME photometry. 
V13: isolated, V light curve has a flat minimum, possibly due to superposition to a brighter star. 
V14: 1.5 magnitudes fainter companion 2.9 pixels away, not in ALLFRAME photometry. 
V15: Fainter companion three pixels away. Symmetric light curve; not sufficient coverage of the 
light curve in F814W to derive a reliable I magnitude.
V16: Fainter companion 1.5 pixels away. V light curve has flat minimum and small amplitude.
V17: two fainter (0.6 and 1.4 magnitudes respectively) companions 2.3 and 2.9 pixels away; not 
in ALLFRAME photometry. 
V18: flat I light curve. 
V19: 0.9 magnitudes fainter companion 2.4 pixels away; not variable from ALLFRAME photometry. 
V20: crowded region, three companions between 3 and 5 pixels away. Not in ALLFRAME photometry,
flat I light curve.  
V21: crowded region, three companions between 3 and 5 pixels away.  Eclipsing variable? 
V22: crowded region, several companions within 5 pixels. Not in ALLFRAME photometry, I light
curve does not phase with V light curve. 
V23: two fainter (.2 and 1.1 magnitudes) companions 2.5 and 2.2 pixels away; not in ALLFRAME
photometry.
