JWST NIRSpec/MSA trace libraries and detector models

Reference data needed for forward modelling of NIRSpec MSA data, as described in de Graaff et al. 2023 (https://arxiv.org/abs/2308.09742).<br> <br> This dataset contains a library of traces for each NIRSpec filter/disperser combination, providing a mapping from a microshutter s_{i,j} and wavelength to the position in the detector plane, and includes the rotation angle of the slitlet with respect to the trace in the detector plane.<br> Other files provide information on the detector, such as the pixel size and the kernels used to model the inter-pixel capacitance. These data are designed to be used together with the NIRSpec MSA forward modelling code msafit, which is available publicly on github: https://github.com/annadeg/jwst-msafit
