Large modifications of the pk1d routines, and some modifications at the delta extraction. The main point of the PR is to implement an estimator of the one-dimensional power spectrum based...
This should propagate the read values of tile, petal and night values to the delta files, if they are available in the catalogue. They are stored as a string. Lines...
Numpy 2.0 is now in beta and will have ABI breaking changes, i.e. not be fully backwards compatible. See current release notes here: https://github.com/numpy/numpy/releases/tag/v2.0.0b1 As we rely on both numpy...
The PETAL , FIBERID and TILE are not properly saved in the delta metadata when running with tiles as input. It would be useful to restore this capacity for the...
I was running Picca on mocks and noticed several warnings in the output error files: ``` cat /global/cfs/cdirs/desi/users/font/test_mock_53/picca_on_qq/v9.0.53.100.100/desi-4.124-4-prod/baseline/logs/picca_delta_extraction_lya_fitted-18605671.err /global/common/software/desi/perlmutter/desiconda/20230111-2.1.0/conda/lib/python3.10/site-packages/iminuit/util.py:147: UserWarning: Assigned errors must be positive. Non-positive values are replaced by...
As a lot of the work in picca gets done by scripts in the bin folder, it would be nice to have a readme explaining what each of them does,...
Add metadata to files used for interpolating var_lss obtained from raw mocks. https://github.com/igmhub/picca/tree/delta_extraction_true_continuum/py/picca/delta_extraction/expected_fluxes/var_lss Also figure out if regions other than Lya will be included in the same files, different hdu's...
Here is a list of all the possible correlation that can be calculated in the context of pixels and objects. Please complete the list if something has been forgotten and...
A simplified version of the FVoigt computation, based on the code by @moonlovist. Work in progress.
