| GRB011130 = XRF011130: 2nd Epoch Measurement Source List |
Epoch 1: 10 December, from 00:38 UT - 09:27 UT (30 ksec)
Epoch 2: 20 February, from 10:02 UT - 14:30 UT (16 ksec)
In the table below, we retain the same Chandra names and ordering assigned for our original epoch 1 table. These are the sources within the HETE error region (7.6 arcmin radius [90%]).
That list of sources was determined by running wavedetect on the first epoch data (GCN 1185, 1190). We fixed the wavedetect source locations and compared the first and second epoch data by measuring source counts within a circular aperture defined as the 95% encircled energy diameter plus 2 arc seconds. The second epoch was of a shorter duration, at a slightly offset pointing, and a different roll angle. So, we corrected the exposure for effective area and integration time when comparing the second epoch count rate to that expected from the first epoch, assuming each source remained constant.
Below, E1C denotes the epoch 1 net counts for each source, E1B the epoch 1 background counts estimate, (E2C) the expected epoch 2 net number of counts based on epoch 1, E2C the observed net counts in epoch 2, and E2B the epoch 2 background counts estimate.
