Segmentation fault
I am new to scamp. I have used sextractor on many occasions.. I got the segmentation fault with scamp. I believe I may not be running it properly. In short, first I run sextractor with:
sex -c scamp.sex test.fit
where I have put FITS_LDAC as suggested in .sex file to get cat.fits file as an output catalog with all the relevant fields:
# 1 XWIN_IMAGE
# 2 YWIN_IMAGE
# 3 AWIN_IMAGE
# 4 BWIN_IMAGE
# 5 THETAWIN_IMAGE
# 6 ERRAWIN_IMAGE
# 7 ERRBWIN_IMAGE
# 8 ERRTHETAWIN_IMAGE
# 9 FLUX_AUTO
# 10 FLUXERR_AUTO
# 11 MAG_AUTO
# 12 FWHM_IMAGE
# 13 FLUX_RADIUS
The values look quite reasonable. But when I run scam afterwards with:
scamp cat.fits -c default.scamp
where default.scamp I changed only FWHM_THRESHOLDS from 0.5 to 10 and MATCH_FLIPPED to YES, since in my case I believe the axes are flipped. Anyway, I got the message:
----- SCAMP 2.0.4 started on 2017-06-05 at 13:19:47 with 4 threads

----- 1 inputs:

Segmentation fault: 11
