Code and data used to measure the black hole mass in MRG-M0138

This respository contains code and data needed to reproduce the analysis of the black hole mass in the galaxy MRG-M0138. Specific contents are described in the readme.txt file and include: Code to refine an initial multi-Gaussian expansion by fitting in the image plane Code for the JAM dynamical modeling Inputs to the dynamical modeling, including the measured stellar kinematics, their covariance matrix, and the PSF model. Deflection angle maps computed for the fiducial lens model Code to model NIRSpec wiggles Code to compute the correlation matrix of the second velocity moments (sigma_rms)
