New release: Version 2.8

Dear Pyxel users,

The Pyxel version 2.8 is released.

This release introduces significant updates and new features.

🆕 New model exponential_qe in Charge Generation

Model exponential_qe from Charge Generation has been added.

This model computes the Quantum Efficiency (QE) of a detector based on key characteristics such as: * Front/Back Illumination * Charge Collection Efficiency * Absorption coefficient * Reflectivity * Epilayer thickness * Poly gate thickness

🆕 FITS Header Propagation

It is now possible to propagate the FITS header, read using model the load_image from Photon Collection with a FITS Image data file into the FITS output file(s).

For example, if the FITS file my_image.fits contains a FITS header into its HDU (Header Data Unit) ‘RAW’, you can extract and store it into an output FITS file by using the following YAML configuration:

observation:   # or 'exposure'
  outputs:
    output_folder: 'output'             # <== output FITS file(s) will be save in this folder
    save_data_to_file:
      - detector.image.array: ['fits']  # <== generate at least one FITS file

cmos_detector:
  ...

pipeline:
  photon_collection:
    func: pyxel.models.photon_collection.load_image
    enabled: true
    arguments:
      image_file: my_image.fits         # <== input FITS filename
      convert_to_photons: false
      include_header: true
      header_section_index: 'RAW'       # <== HDU where to retrieve the FITS header (optional)

   ...
