WFCPOSX
This program takes as input an ASTERIX image dataset created by WFCSORT
and reports exposure information for any location within the image.
The quoted effective exposure is the value by which a raw count derived
at the location should be divided in order to produce a count rate
corrected to the axis of the instrument at the epoch of the data set.
In addition the program displays the efficiency of the detector for the
epoch of the data set relative to the launch efficiency. This relative
efficiency may be used to increase a measured flux to that appropriate
to a non-degraded detector. The exposure calculation works in a similar
manner to that in the WFCEXP program described above.
