pysersic - pysersic v0.1.4

Minor changes to the codebase for increased usability, including

• coersion of input arrays to float32 to prevent jax array warnings
• adopt theta convention that 0 deg == up in each image
• addition of equinox modules

pysersic - v0.1.2

Add several useful user warnings, in particular targeting cases where users - input a PSF image larger than their galaxy cutout - input a weight-map that has values significantly different than the image rms - input a PSF image that is not (roughly) normalized - input a mask that masks more then 50% of pixels in the cutout (usually not an intended use).

pysersic - Initial Release

The initial release of the pysersic code. Allows users to fit either single or multi-source galaxy images using gpu-accelerated, gradient-enabled samplers via jax and numpyro. Has several Rendering modes, including real, Fourier,and hybrid real-Fourier methods.
