widefield-plate-solver 0.1.4

An astronomical image plate solving package.

# Widefield Plate Solver

This package provides tools for plate solving wide field astronomical images. Its main difference with using Astrometry.net’s solve-field directly is that it can also default to Astrometry.net’s API if requested.

## Installation

To install the package, run: `bash $ pip install widefield-plate-solver `

## Usage

### as a script

After installation, you can use the command widefield-plate-solve from the terminal:

`bash $ widefield-plate-solve <fits_file_path> --use_api ` Replace <fits_file_path> with the path to your FITS file. Use the –use_api flag to use the Astrometry.net API for plate solving: your environment variables will need to contain your API key.

`bash $ export astrometry_net_api_key="your_nova_astrometry_api_key" ` Not using –use_api will default to your local installation of Astrometry.net, looking for the solve-field command.

For more information on usage, run:

`bash $ widefield-plate-solve --help `

### from python

See the plate_solve function imported from the package:

`python from widefield_plate_solver import plate_solve help(plate_solve) `
