0.6.0 - July 18, 2023

🔧 Fixed

0.5.2 - July 17, 2023

✨ Improved

  • Round up telescope values in headers.

  • Change TRIMSEC and BIASSEC header keywords. Fixed incorrect values due to the three prescan pixels and split TRIMSEC and BIASEC by amplifier.

🚀 New

  • Add suport for spectrograph 3.

  • Support Python 3.11.

✨ Improved

0.3.0 - May 28, 2022

🔥 Breaking changes

  • #3 Many changes, the main ones including:

    • The lvmscp actor now inherits from ArchonActor. There is no archon actor anymore and archon is only used as a library. This is analogous to how yao works.

    • Removed the Supervisor class.

    • lvmscp now has all the archon commands, including an updated expose command.

    • General code clean-up, linting, testing, etc.

✨ Improved

  • Reading sensor and system data is now done during integration using ExposureDelegate.expose_cotasks() instead of during readout, to avoid poetentially out of data information.

  • Improved code to retrieve lamp status from the latest version of lvmnps.

0.1.3 - February 27, 2022

Major updates:

  • *The code structure is modulized. The algorizmatic code is all in supervisor.py

  • *The focus command was roll backed and the user can also make the API and run the sequence

  • *linting, and also minor bugs were fixed.

  • *there was a error the the arc lamp was wrongly added on the fits header.

0.1.2 - January 17, 2022

Major updates:

  • *The cluplus is added for the modulization of the package

  • *The focus command was removed since the user can make the API and run the sequence

  • *docstrings were added on the functions

  • *all of the commands are added on the module.py, so the user can run the API of the lvmscp as test.py
