The XRT all-sky survey

For the XRT survey only the PSPC was used. With a field of view of 2 and a nominal survey rate of 1 per day a celestial position in the plane of the ecliptic was visible for approximately two days. During this period of two days any source was viewed up to 30 times for up to 32 s each time, i.e., the duration of a scan through the center of the XRT field of view.
