Note on diffuse response calculation: (OBSOLETE)gtdiffrsp is called three times in succession. The first time with IRF P7_v2_diff and evclsmin==8, followed by IRF P7_v2_extrad and evclsmin==9, and finally IRF P7_v2_datac and evclsmin==10. The resulting FT1 file has six columns of diffuse response, two columns (galactic and extragalactic response) for each of the three IRFs. This creates a non-standard FT1 file by FSSC standards as they expect only five diffuse response columns.(OBSOLETE)

- 8/31/2010 - With P120-MERIT files nicely distributed across xroot servers, there were no xroot limitations to the processing. After the update to makeFT1, there was no longer an issue with overloading /u38 ($PWD). The next bottleneck was the pipeline processing itself. This task consists of three batch jobs and four scriptlets; it was observed that the pipeline allowed hundreds of jobs to dwell in the READY state for extended periods of time, thus making it impossible to keep LSF saturated. Nevertheless, the maximum number of simultaneous jobs approached 2000. The task essentially completed in 6 hours, although some lingerers kept 'running' for another nine hours (mostly in SSUSP).
