augment_xylist Failed

[Rafael Morales]

Hi Dustin,

I'm using this solve-field version:   Revision 0.86-36-g830d6705, date Wed_Oct_6_10:28:43_2021_-0400.

Using my own-cooking GAIA EDR 3 indexes.

Solving a list a images locally, sometimes this error appears:

solve-field.c:1279:main augment-xylist failed

 augment-xylist.c:715:augment_xylist Failed to find size of FITS image "26": got NAXIS1 = -1, NAXIS2 = -1

The image is solved in any case.

Is it just a warning that can be ommited?

Thanks in advance.

Rafa.

Hi,

Sorry for the slow reply, this got put in Spam by my gmail...

This looks sort of like you have an extra "26" in your command-line arguments and it's trying to read it as a file?  Could you please send the full command-line arg you're running?

That's not a warning I've ever seen before.

cheers,

Hi Dustin,

 

  Probably you are right and is a problem in the calling parameters.

  I call "solve-field" using parallel (https://www.gnu.org/software/parallel/) to solve massively images in local using a script.

  I've modified that script and I did not see the weird message again, but if it appears again I will take note of the parameters.

Best regards,

Rafa.

Hi Dustin,

  Here you can find a reproducible test that shows the error message regarding unknown image "20".
  If CPU time is increased, the image is solved, and not error is shown.

The --ra and --dec arguments MUST have colons between the HH:MM:SS / DD:MM:SS.

Because solve-field is expecting only *one* argument (one "word") following --ra, it's doing:

"--ra 17 20 38 --dec -15 20 36"

--> ra = 17

--> dec = -15

additional arguments must be names of image files to load: "20", "38", "20", ond "36".

cheers,

Ok, my fault. Thank you Dustin
