... 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. ...
