Question [Free format]:

I provide to the task " xissimarfgen" the input information requested as it follows:

xissimarfgen
xissimarfgen version 2006-08-02
Written by Y.ISHISAKI (TMU)
Instrument Name (XIS0,XIS1,XIS2,XIS3)[XIS0] 
source mode (SKYFITS,DETFITS,J2000,SKYXY,DETXY,UNIFORM)[J2000] 
source position R.A. (deg)[272.163833]
source position DEC. (deg)[-20.410972]
number of ARF regions[1] 
region mode (SKYFITS,DETFITS,SKYREG,DETREG,etc)[SKYREG] 
region file #1[xis0_src_arf.reg]xis0_src_arf.reg
limit mode (ACCURACY,NUM_PHOTON)[MIXED]
number of photons for each energy bin[400000]
calculation accuracy for each energy bin[0.005]
input pha file[xis0_src.pha]  xis0_src.pha
XIS det-coordinates mask image file[none] 
input GTI file[ae401092010xi0_0_3x3n000a_cl.evt]
input attitude file[/auxil/ae401092010.att]
input rmf file[xis0.rmf]   
energy step file[estep-default.list] 

The region "xis0_src_arf.reg" is in the coordinate system "Physical"(is this correct?) and the rmf "xis0.rmf" was created with the XIS RMF generator ftool "xisrmfgen" (beta-release). I access the HEASARC CALDB remotely.
The result follows.

Task xissimarfgen 2006-08-02 terminating with status -1

Am I doing something wrong?

Annotation: using a region in the coordinate system "Image", the simulation starts but, after a very long time, the task creates an arf that doesn't work.

I found the problem with xissimarfgen: when the task reads the region xis0_src_arf.reg it finds 'physical' instead of 'circle(...)'. During the analysis of the Suzaku data I changed the ds9 version from 3.0 to 4.0, and the latter writes the region files in a slightly different way (that's why the simulation started using the region in the 'image' region: it was generated using the DS9 3.0). 2006-11-10 Accept
