Dear Pyxel users, The Pyxel version 2.0 is released ! This is a major release of Pyxel that brings number of new features such as support for multi-wavelength. Version 2.0 brings a number of bugfixes, improvements and deprecations. Breaking Changes Removed models The deprecated models in optics and photon_generation model groups are removed. The deprecated model simple_aperture in photon_collection is removed. New unit for wavelength Parameter wavelength in model optical_psf in photon_collection is defined in nanometer instead of meter.

Dear Pyxel users,

The Pyxel version 1.15 is released.

This release brings a number of bugfixes and improvements.

The bucket Photon can now be 2D or 3D (with additional dimension wavelength).

A new function pyxel.display_scene() was added to display the scene, which is generated by models inside the Scene Generation.

New models were added to Photon Collection and Charge Generation that can manage multi-wavelength photons.

The following new models were added:

• load_wavelength_psf in Photon Collection.

• optical_psf_multi_wavelength in Photon Collection.

• apply_qe_curve in Charge Generation.

• conversion_with_3d_qe_map in Charge Generation.

Breaking changes:

The model argument pixel_scale was moved to the Detector.geomerty.

The model aperture in photon_collection is deprecated and will be removed in Pyxel 2.0. Please use simple_collection instead.

See more details and changes in the changelog.

Dear Pyxel users,

The Pyxel version 1.14 is released.

This release brings a number of bugfixes and improvements.

The functions pyxel.exposure_mode(…), pyxel.observation_mode(…) and pyxel.calibration_mode(…) are deprecated and will be removed in Pyxel 2.0.

These functions are replaced by pyxel.run_mode(…).

Dear Pyxel users,

The Pyxel version 1.13.1 is released.

This release brings a number of bugfixes and improvements.

With the new breaking changes in version 1.13 the pixel array was reset also when using non-destructive readout mode. This new release fixes the bug. The error message is improved when an array is not initialized and the documentation for the model groups is updated, such that the user is better informed.
