The help file says:"
SYNTAX
psextract events bgevents root aoff bgaoff [gtype] [gspec]
[verbose]"
This implies that one can set the bgaoff parameter. However, when I do a
plist, I get no evidence that bgaoff exists:
cfa261-268: plist psextract
Parameters for /home/emk/cxcds_param/psextract.par
events =
acism00651N000_evt2_clean_GainCorr_norand_flt1.fits[sky=region(cntr.reg)]
Source events specification
bgevents = aciss_C_s3_bg_evt_191000.fits[sky=region(B1a.reg)]
Background events specification
root = cntr_maximbk Root name for output files
aoff =
/data/emk/raq/obs651/ACIS_FULL/out/acism00651_001N000_aoff1.fits Aspect
offsets file
(ptype = pi) pha or pi
(gtype = NUM_CTS) Spectrum grouping type (NONE, BIN,
SNR, NUM_BINS, NUM_CTS, or ADAPTIVE)
(gspec = 25) Spectrum grouping specs
(NONE,1:1024:10,etc)
(verbose = 5) Debug Level(0-5)
(mode = h)
Then, when I run it, I get messages saying there are missing columns:
cfa261-270: rm psextract_cntr_maximbk.log
rm: remove psextract_cntr_maximbk.log (yes/no)? y
cfa261-271: psextract > psextract_cntr_maximbk.log
expr: non-numeric argument
dmextract: processing input file
acism00651N000_evt2_clean_GainCorr_norand_flt1.fits[sky=region(cntr.reg)]
extraction on NUM_CTS
# 15170: dmextract: dmextract: No column NUM_CTS in block EVENTS

# 15170: dmextract (1) is: exit_upon_error->NULL

: Error 0
# 15181: dmextract (1) is: exit_upon_error->NULL
pquery: invalid enumerated value : type
Then I try again with the bgevents file the same as the events file,
and it says:
cfa261-276: psextract
********* ERROR: Using same events files and different AOFF files for
source and background
cfa261-277: plist psextract bgaoff

Source events specification
bgevents =
acism00651N000_evt2_clean_GainCorr_norand_flt1.fits[sky=region(B1a.reg)]
Background events specification
root = foo Root name for output files
aoff =
/data/emk/raq/obs651/ACIS_FULL/out/acism00651_001N000_aoff1.fits Aspect
offsets file
(ptype = pi) pha or pi

(verbose = 5) Debug Level(0-5)
(mode = h)
So it seems to think it has more than one aoff file, but I never gave it
more than one!
Any suggestions?
