panstamps

A python package and command-line tools to download stacked and/or warp image stamps from the STScI PanSTARRS image server.

note

If working with warped PS1 images then you need to work off a machine that has an IP address whitelisted by the Pan-STARRS1 data archive, otherwise only stacked images will be available to you. Also w-band images are not (yet) accessible from the data archive.

Installation

The easiest way to install panstamps is to use pip:

pip install panstamps

Or you can clone the github repo and install from a local version of the code:

cd panstamps
python setup.py install

To upgrade to the latest version of panstamps use the command:

pip install panstamps --upgrade

Troubleshooting on Mac OSX

panstamps uses pillow (a fork of the Python Imaging Library) which requires some external libraries.

If you have issues running panstamps on OSX, try installing Homebrew and running:

brew install libtiff libjpeg webp little-cms2

Development

If you want to tinker with the code, then install in development mode. This means you can modify the code from your cloned repo:

git clone git@github.com:thespacedoctor/panstamps.git
cd panstamps
python setup.py develop

Pull requests are welcomed!
