... To help you get the necessary calibration data in the least observing time, the planning program generates a schedule of required observations. A considerable amount of photometric expertise is built into this program, so that observers without much photometric experience can confidently adopt its recommended defaults, and obtain a plan that should be satisfactory for most photometric observing programs. ...

... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars,   total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...
