[ascl:2409.020] pyRRG: Weak lensing shape measurement code
Harvey, David R.; Massey, Richard
pyRRG measures the 2nd and 4th order moments using a TinyTim model to correct for PSF distortions. The code is invariant to the number exposures and orientation of the drizzle images. pyRRG uses a machine learning algorithm to automatically classify stars and galaxies; this can also be done manually if greater accuracy is needed.
