Version History

v0.27.4 (2024-02-12)

Performance Enhancement

• In /auxtel/latiss_wep_align.py, change how the source selection is checked when running wep. Instead of relying on the intra-focal image as the basis, compute the distance to the boresight and either use the source detected (if it is close enough to the bore sight) or use the source detected for the other image. It will also raise an exception if both sources are too far from the boresight.

  In auxtel/latiss_base_align.py, add gains when converting from wavefront error to hexapod correction. (DM-42690)

v0.27.3 (2024-02-02)

New Features

• In auxtel/latiss_base_align.py added self.next_supplemented_group_id() call so that intra and extra focal images have the same group id. (DM-41684) (DM-41684)

v0.27.2 (2023-12-14)

New Features

• In auxtel/correct_pointing.py, add config to reset the AOS offsets. (DM-41870)

Bug Fixes

• Fixed a bug in latiss_base_align.py module when trying to flush the ataos.evt_detailedState event before resetting resetting the hexapod to its initial position. That flush was not needed, redundant and it was causing an error. (DM-41718)

• In auxtel/latiss_acquire_and_take_sequence.py, add floor to y-value of final blind offset position to prevent target landing off of detector. (DM-41870)

• In LatissBaseAlign:

  • Fix issue in configure method accessing self.config instead of config.

  • Change default rotator strategy from SkyAuto to PhysicalSky.

v0.17.0

• Add new metaclass, LatissBaseAlign, which contains the generic actions required to execute a curvature wavefront error measurement, abstracting the computation part. The meta script performs the following actions:

  • slew to a selected target,

  • acquire intra/extra focal data by offsetting the hexapod in z,

  • run a meta function that computes the wavefront errors,

  • de-rotate the wavefront errors,

  • apply a sensitivity matrix to compute hexapod and telescope offsets,

  • apply comma and focus correction to the hexapod and pointing offsets.

  Therefore child implementations are only left to implement the function that computes the wavefront errors.

• In LatissCWFSAlign, use new meta script LatissBaseAlign. This basically removes all the code that was moved from LatissCWFSAlign into LatissBaseAlign.

• Add unit tests for new LatissWEPAlign script.

• Add new LatissWEPAlign script that implements LatissBaseAlign script by using the wavefront estimation pipeline task. This is the same code we will use for the main telescope and is designed as a DM pipeline task, rather than a standalone python code as CWFS. Note that the code is developed to use most of the processing done by the cwfs version using, for instance, BestEfforIsr to rapidly process the raw frames and QuickFrameMeasurementTask to find the donuts. The data is then passed along to the pipeline task for processing. Also, note that the processing is done in parallel in a separate python process. This guarantees that the main processing (driving the Script) is kept free of load. The amount of data passed from one process to another is rather small in this case, only the pipeline task result and the quick frame measurements are returned.

• In LatissCWFSAlign unit test:

  • rename run_cwfs -> run_align

  • rename sensitivity_matrix -> matrix_sensitivity

  • rename total_coma_x_offset -> offset_total_coma_x

  • remove __all__

  • add missing line on license header.

• In LatissCWFSAlign fix missing space in error message.

v0.16.0

• First version with documentation.

• Updated latiss_cwfs_align to handle case where the applied offsets to the ATAOS are too small for a correction to be applied.
