A package for performing CCD data reduction and processing.
Collection(name TBD?) type
Some kind of container for holding the different images. I think a good idea would be to have something that can be given data directly as arrays, or can be given as filenames, or can even be given by directories/globs. The data should be accessed lazily (unless loaded in directly).
This will be what is passed to the high-level routines for reduction
Pipeline(name TBD) type
Having some way of storing/serializing a processing pipeline. This should be something that can be created independently of data and then run on a Collection
- Statistical: lots of image statistics will need to be calculated. For now those may already exist, or might be in a different package, might need to be added here, or might need to be added somewhere like
AstroBase.jl - Cosmic-Ray Detection
- Background Subtraction
- Flat-Fielding
- Bias Subtraction
- Non-linearity correction
- Image Registration (not in here, should make a separate package)
- Stacking
- Overscan subtraction
- Morphological changes (trim, pad, ... probably already in Images.jl)
- Offer many ways to output
- Full integration with Unitful
- Variance calculations
- Good mix of low-level, high granularity functions and high-level methods for chaining processing together. I would love to see something where you can denote
bias |> dark |> register |> median_stackor seomthing where it seesbiasand will automatically debias the darks and the science frames, without specifying for each type.
