*qpsim* - Generate Simulated Event List

A simulated HRI event list is generated from a set of user-specified source intensities, shapes and positions. The source specification is input into an iraf table using tcreate and the PROS-supplied format description. Please refer to the qpsim help file for detailed information on the source parameters. Briefly, they are: x, y, counts/rate, intensity (as counts/rate), prf-type, prf-parameter:

tt> tcreate
name of table to be created:    (source.lis)
name of file containing column descriptions:  (xspatialdata$srclst.cd)
name of file containing data (STDIN):
Give table data ... then newline & EOF to finish.
4096 4096 rate 0.5 ros_hri INDEF
5000 2500 counts 300 ros_hri 20

tt>

Once this table has been created, qpsim is run to generate the qpoe file: Note that the ``bad attribute name `time''' message can be ignored, see help file.
