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.
