Tired of sky subtraction residuals? ZAP them!
ZAP is a high precision sky subtraction tool which can be used as complete sky subtraction solution, or as an enhancement to previously sky-subtracted MUSE data. The method uses PCA to isolate the residual sky subtraction features and remove them from the observed datacube. Future developments will include modification for use on a variety of instruments.
The last stable release of ZAP can be installed simply with pip:
pip install zap
Or into the user path with:
pip install --user zap
