CPU time limit reached

[Deckers Maxime]

Hi,

I have a few images that have been repeatedly failing (with CPU time limit reached) using the web service. I have tried changing the scale (tried both 1-180 deg and 3-9 arcmin) and specifying the ra and dec of the centre of the image, but neither fixed the problem. 

I have tried using SourceExtractor instead of the built in source detector, but this also does not work. 

This is one example (http://nova.astrometry.net/user_images/5614589#original) 

Thanks!

Hi,

Note that your image is actually about 2.8 arcminutes on a side, so the "3 to 9 arcmin" option would not have worked.  But even putting in the correct scale, I fail to get a solution on the web version.  However, using the Gaia-based index files (specifically index-5200-18.fits for this image), I do get a solution.

I put the WCS file here for you, https://portal.nersc.gov/project/cosmo/temp/dstn/1.wcs

If you happen to be able to run the command-line version on your computer, you'll need at least that index file,

  https://portal.nersc.gov/project/cosmo/temp/dstn/index-5200/LITE/index-5200-18.fits

and I used:

  solve-field ~/1.fits --ra 21 --dec 13 --radius 1 --scale-low 0.11 --scale-high 0.13 --scale-units app --config index-5200.cfg -v --downsample 2 --continue --crpix-center

and the file index-5200.cfg contains:

add_path /YOUR/PATH/TO/index-5200
indexset 5200

#autoindex
inparallel

Hope that helps!
