weightmask
weightmask reads a detrended FITS or MEF science image and writes a per-pixel weight, quality mask, inverse-variance map, and sky.
Those products are for any measurement that should ignore bad pixels and down-weight the rest: coaddition, shape measurement, forced photometry, profile fitting, and difference imaging.
Install
pip install weightmask
Python 3.10+. The canonical weightmask.yml is bundled in the wheel and sdist.
Copy it into a working directory with:
python -c "from weightmask.config import copy_default_config; copy_default_config('weightmask.yml')"
Pixi (development):
git clone https://github.com/astroai/weightmask.git
cd weightmask
pixi install
