subtract_psf

• generates mock reference and target stellar observations with NIRSpec's Integral Field Unit (IFU)
• can use real spectral data to inject a companion brown dwarf into the target observations
• aligns images and employs KLIP on reference observations to project the PSF of each target's background star
• uses reference star differential imaging to attempt to subtract the background star from each target image
• can visualize the results in a Jupyter notebook or export a directory of FITS images for viewing in DS9

To install locally:

git clone https://github.com/ojustino/subtract_psf
cd subtract_psf
pip install .

Add -e before the period in the final line if you intend to make changes to the source code.

(If you get import errors in Python even after trying the above, navigate to your cloned subtract_psf directory and try python setup.py develop instead.)

Example usage:

See introduction.ipynb for a quick start and inject_kappa_and.ipynb for a worked example.
