Just a script to download and install just the bare minimum of astrometry.net.
Note it requires that you give astrometry.net a binary fits file of the star locations. You won't be able to find stars using the built-in astrometry.net search tool.
Building and installation of the required astrometry.net binaries is decribed below. Once these are installed, from python you can run the following command, for example:
solve-field --overwrite --uniformize 0 --no-remove-lines --no-plots -o [basefilename] -X X -Y Y --sort-column FLUX --width 3352 --height 2532 [basefilename].xyls
where [basefilename] is just the base name for the input binary fits file (described here) and the basename for all the output files.
You'll need to install the following packages on a relatively fresh install (here shown for OSX homebrew):
brew install pkg-config
brew install md5sha1sum
brew install cfitsio
You might need to install stuff described here. But go ahead and try running it first to see if anything fails during compilation.
Download some astronomy.net index files for wide-field images here. Or for all angular sizes here.
You should just be able to run the following on your command-line:
git clone https://github.com/lspitler/astrometry.net-lite.git
cd astrometry.net-lite
bash install.bash /path/to/binaries /path/to/astrometry.net/index/files
Replace /path/to/binaries with where you want the executable (and astrometry.cfg) files to live and replace /path/to/astrometry.net/index/files with path where the astrometry.net index files are located.
