Installation

pip install git+https://github.com/AlexKurek/ds9crop in not working!

Global Install

Install using pip:

git clone https://github.com/AlexKurek/ds9crop.git
cd ds9crop/
sudo pip install .

or manually (deprecated but working):

git clone https://github.com/AlexKurek/ds9crop.git
cd ds9crop/
sudo python setup.py install

and add it to DS9 like any other analysis commands (http://ds9.si.edu/doc/ref/analysis.html).

Single user install

git clone https://github.com/AlexKurek/ds9crop.git
cd ds9crop/
pip install .

Note that the .ds9 file is copied to ~/.local/ds9/ instead of /usr/local/ds9/.

Usage

Start DS9 e.g. like this:

ds9 /patchToFITSfile/file.fits -xpa unix -regions shape box -scale limits -0.001 0.01 &

Create a box- or circle shaped region and simply press 'x' to save it as both FITS and 16-bit png files. ds9crop will try to connect to the DS9 instance via the XPA server to get the current scale limits. If this doesn't work, <-0.001, 0.01> will be set in the saved png file and in both popup windows.
