Why does dmextract convert arcseconds to arcminutes when I use pset?
unix% pset dmextract \
infile='infile.fits[bin sky=ellipse(161.18d,-59.71d,2.56",1.71",34.40)]'
unix% plist dmextract
Parameters for /home/username/cxcds_param4/dmextract.par
#--------------------------------------------------------------------
#
# DMEXTRACT -- extract columns or counts from an event list

#--------------------------------------------------------------------
infile = infile.fits[bin sky=ellipse(161.18d,-59.71d,2.56',1.71',34.40)] Input event file
This is a bug in the parameter interface, caused by the double quotes used to denote arcseconds. As a workaround, create a one-line stack as the input to the tool:
unix% cat stack.lis infile.fits[bin sky=ellipse(161.18d,-59.71d,2.56",1.71",34.40)] unix% pset dmextract infile=@stack.lis
See ahelp stack for more information on how CIAO treats stack inputs.
