... Optical photometric data were taken of fields encompassing all these sources during a total of seven telescope runs. ... The initial goal of the photometric observations is to follow up the X--ray sources, assign them colors in a standard system, so that the observed objects can be placed on a color--magnitude diagram. This can be used to verify that the X--ray sources are indeed PMS stars. ... Aperture photometry was performed using the APPHOT package in IRAF. ...

... They are the offset in arcseconds for the x and y inst plane offset, the exposure time in seconds, and the number of exposures at each position. ... A point about offsets should be made here. The dither program uses absolute instrument plane offsets, so you should use object plane offsets to center up on the chip so that the script starts from where you centered up. INST and OBJ offsets are independent so an object offset will not be zeroed out by and inst plane offset, just added to it. ...
