SHAMFI is designed to fit images out of radio-frequency interferometers using shapelet basis functions (Refregier 2013). It's currently limited to fitting a FITS file, such as those output by WSClean. It can output models that work with the calibration and imaging software the RTS (Mitchell et al. 2008) and the simulator WODEN, so that the image based fits can be used to generate visibilities.
This repo includes:
| Script | Overall Function |

mask_fits_shamfi.py |
Splits a FITS image into multiple images using gaussian masks |
subtract_gauss_from_image_shamfi.py |
Subtracts specified gaussians from an image to make fitting shapelets easier |
combine_srclists_shamfi.py |
Combine multiple RTS/WODEN source catalogues into one |
convert_srclists_shamfi.py |
Convert between RTS and WODEN source catalogue formats |
