I use the Astrometry.net web service by python code (client.py.) Is there in any way to give the constrain like field of view, pixel size or magnitude?

Best regards,
Kang Ryoungwook

Hi,

If you run
    python3 client.py -h
you will get the help message.

To give the image size, you want to use "--scale-units", "--scale-lower", and "--scale-upper".

For example, to say that your pixel scale is between 1.0 and 1.2 arcseconds per pixel,

--scale-units arcsecperpix --scale-lower 1.0 --scale-upper 1.2

cheers,
dustin


  --scale-units=SCALE_UNITS
                        Units for scale estimate ("arcsecperpix",
                        "arcminwidth", "degwidth", or "focalmm")
  --scale-lower=SCALE_LOWER
                        Scale lower-bound
  --scale-upper=SCALE_UPPER
                        Scale upper-bound
