Azimuth/Elevation converter for Astrometry.net

Note: If you want to work with the intermediate steps (source extraction) or photometry, see my AstroPy-based examples.

Prerequisites

Astrometry.net >= 0.67

or, use the astrometry.net cloud service–handy for Windows users

Installation

python -m pip install -e .

Astrometry.net index files

If you use astrometry.net on your PC, you may need to install the index files and setup your config file to point at them:

downloadIndex.py

Command line options

--h5

write az/el et al to HDF5

--mat

write az/el et al to .mat Matlab save file

--png

write az/el et al to PNG

-h

to see all the options you can use

Examples

Astrometry.net installed on your PC:

python PlateScaleFITS.py myimg.fits -c 61.2 -149.9 -t 2013-04-02T12:03:23Z --h5 --png

gives HDF5 .h5 with az/el ra/dec and PNG plots of the data. Both files contain the same data, just for your convenience.

The 61.2 -149.9 is your WGS84 coordinates, 2013-04-02T12:03:23Z is UTC time of the picture.

wcs.fits from the Astrometry.net WEBSITE:

first rename wcs.fits to myimg.wcs:

python PlateScaleFITS.py myimg.wcs -c 61.2 -149.9 -t 2013-04-02T12:03:23Z --h5 --png
