... Post-Observation . ... This MJD value (for ACCUM mode observations) is stored in the EXPSTART keyword in the science data headers ( *.d0h , *.c1h ). ... The best estimate of when a RAPID observation started is the PKTTIME of the first calibrated science packed ( *.c1h[1] ) minus the sample time of the observation, which, in this instance, can be found in the STEPTIME keyword. ... For ACCUM mode observations, a second UDL is dumped at the end of the exposure and prior to reading out any science data....

... The science from both these missions contributed to three of the Nobel Prizes Giacconi (2002), Mather, and Smoot (2006) - awarded for NASA-based science. ... We encourage NASA to seek new launch capabilities to fill this strategic gap in moderate lift rockets to enable the Explorer program to continue launching missions with significant science payoff but reduced costs and timescales compared to large strategic missions. ... 18 Appendix B: Explorer Missions 1989-present (From PILMSS) No . ...
