###########################################################
## process `evt2 file' generated by `chandra_repro' ##
## to produce a `clean evt2 file' ##
## (remove point source and flares) ##
## for later image and spectral analysis ##
## ##
## NOTES: ##
## based on previous `ciao_process_evt2.sh' ##
## support ACIS-I(chip: 0-3) and ACIS-S(chip: 7) ##
## determine by check `DETNAM' for chip number ##
## if `DETNAM' has `0123', then `ACIS-I' ##
## if `DETNAM' has `7', then `ACIS-S' ##
