Astronomical Tasks for Tests of X-Ray Optics in VZLUSAT-1 Nanosatellite

Table 4

Estimations of count-rates per second of selected observational candidates for X-ray optics with TimePix sensor onboard VZLUSAT-1 mission. Only the observational candidates with estimated chance of catching one photon per one minute are shown; the other candidates from Table 1 can be computed from (8).
