The long flight time, the perfect operation of all systems, and the wide
field-of-view of the Compton telescope LXeGRIT, which was flown this time
without any shields, allowed us to obtain data on all MeV gamma-ray sources
within ~45 deg zenith angle. Our main focus is imaging of the Crab nebula, but
other strong sources such as 3C273 or Cygnus X-1 have also been in the
field-of-view. We collected a total of almost 40 GB of event data, of which
about 80% have been stored onboard, and the rest downlinked through two 500
kbps telemetry channels.
We are looking forward to our next steps in analysing all the data received.
Many thanks to the NSBF launching team!
The campaign started of course long before the arrival in Ft. Sumner:
Acceleration of the data acquisition system and improvements of the trigger
system, together with several other improvements since the 1999 flight kept us quite busy. The system was tested and calibrated during runs at Nevis Laboratories and finally at the NSBF site in Ft. Sumner.
