Fortran Runtime Error

[GarrettZills]

Hello all,

When I run the following set of commands:

erbox
compress_flag="N"
detmask_flag=Y
expima_flag=Y
emin=500
emax=10000
bkgima_flag=N
ecf=1
boxsize=20
images="image_comb.fits"
boxlist="boxlist_comb.fits"
expimages="expmap_comb.fits"
detmasks="detmask_comb.fits"


I am just selecting a region of interest and generating an image, exposure map, and detmask, then running the erbox command with the specified files and receiving this error.

Index '10' of dimension 1 of array mask above upper bound of 9

Error termination. Backtrace:

Thank you

Dear Garrett,

it seems you have discovered a bug in erbox which causes a crash when a large value of the task parameter boxsize is used.
This parameter sets the size of the detection box (side_length = 2*boxsize+1).
We recommend to use the default value boxsize=5. In case you need larger detection boxes (e.g. for the detecion of extended sources) you may set the parameter nruns to e.g. =3. With this setting erbox will perform 3 consecutive runs and apply a 2x2 rebining of the input image between the runs.
With the default setting boxsize=4 and nruns=3 the effective box sizes are 9, 18, and 36 image pixels.

I hope this answer solves your problem.

Best regards,
Georg Lamer
