Lentils

A lightweight Python implementation of our gravitational lens modeling code.

TODO

• GPUs
• Test BCB convolution for odd-size grid
• Concatenating explicit matrices
• Make space data shape vs. pixel shape cleaner! (or just keep track better)
• Broadcasting to full data shape, including channels and stokes
• Joint modeling of multiple data sets!!!
• Mask as part of VisibilitySpace
• All TODOs in code
• Documentation!!!
• Clean up unit tests, split into more manageable files
• Re-organize sub-modules ('spaces', 'util'?)
• Move misc operators and CSR matrices to their own files
• Use 2F1 series for all deflection computations
• Regularization operators
• Solver framework
• scikit-sparse for Cholesky and solvers
• Duck typing everywhere... quit typechecking function args!
• Clean up dependencies in setup.py
• Merge all c code into one backend module?
