... 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: . ...

Statistics from S. Pesci and P. Mazza logbook. I began my visual hunting program in 1991, after some ten years of variable star observing and deep sky. My patrol galaxies were some one hundred circumpolar galaxies, which were suveryed with a 45cm home made Dobsonian. ... These are checked on average 10-15 times a year, during 35 to 45 nights (numbers depend much on weather), mostly on weekends and holidays.

Searching for an Optimal Strategy to Intensify Observations of the Southern ICRF sources in the framework of the regular IVS observing programs ? ... We found that adding more observations of southern sources to the standard schedule causes a slight degradation of some geodetic products and a slight improvement of others, depending on the number of added southern sources. ... As a consequence, the number of observations of the southern sources is very small. ...
