JWST NIRSpec/MSA PSF libraries

This dataset contains libraries of model PSFs for the JWST/NIRSpec MSA, as described in de Graaff et al. 2023 (https://arxiv.org/abs/2308.09742). We provide one library for each NIRSpec disperser, for a single-shutter and triple shutter configuration (1x1 and 1x3, respectively). The PSFs were computed at the centre of MSA quadrant 3 (shutter (185,83)). The libraries contain PSF images at a range of different wavelengths and intrashutter positions. Libraries can be used in combination with the software msafit, in particular the PFSLib class. The software is available publicly on github: https://github.com/annadeg/jwst-msafit
