Problem with large files (18 Sep 2012)
chandra_repro uncompresses files into memory to be written back out to disk. With large files, this can exhaust system resources and cause the script to fail with a non-informative error message
Unable to read evt1 file # chandra_repro (09 April 2012): ERROR read error
chandra_repro will use the uncompressed version of the file so the easiest work around it to gunzip the files before running chandra_repro
unix% gunzip primary/*gz secondary/*gz
dsAPEPULSEHEIGHTERR -- WARNING: pulse height is less than split threshold when performing serial CTI adjustment.
The following warning may be displayed when running chandra_repro on an ACIS observation
# acis_process_events (CIAO): The following error occurred 2 times: dsAPEPULSEHEIGHTERR -- WARNING: pulse height is less than split threshold when performing serial CTI adjustment.
As is discussed in the acis_process_events bug page, this warning can safely be ignored as long as the number of times printed is small compared to the total number of events.
