All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.4.1] - 2024-02-11

Added

  • univariate_psf_frame, univariate_multi_psf_frame and bivariate_psf_frame functions now also return the updated mask table -- the updates being including those points which were identified by sigma clipping performed while fitting 1D/2D splines.
  • Added a function table2frame in SingleOrderPSF class to convert back 2D frames from 1D pixel table generated by norm_flux_coo.

[0.4.0]

Changed

  • Row-by-row and column-by-column background subtraction function now also return the subtracted background.

Added

  • Functions to perform polynomial background subtraction along rows and columns.
  • Function to perform a 2D background subtraction.

[0.3.0]

Changed

  • Created a class for extracting psf frame for single order spectral data. This clss combines flux_coo, norm_flux_coo, univariate_psf_frame and bivariate_psf_frame functions.
  • Changed the name of psf_extract to optimal_extract to avoid confusion.
  • Updated docstrings
  • Removed "oversample" in y (column) direction.

Added

  • Function to produce PSF using multi-column 1d spline fitting in SingelOrderPSF class.
  • Functions to trace the spectrum in the data in reduce.py.

[0.2.0] - 2023-02-24

Added

  • Added function to perform background subtraction.
  • Created reduce.py
  • Function to generate PSF frame using bivariate spline fitting to the whole dataset.
  • Function to extract spectrum by fitting psf frame to the data.
  • Function to generate psf frame using univariate spline fitting to the whole dataset.
  • Functions to build a pixel array list and its normalized version.
  • Univariate and bivariate spline fitting functions

[0.1.0] - 2023-02-10

Added

  • Aperture extraction function in extract.py.
  • CHANGELOG.md created
