AAT UHRF

Overview

This file summarizes several instrument specific settings that are related to AAT/UHRF.

Wavelength Calibration

UHRF has many wavelength setups, and the wavelength calibration must be performed manually for each setup using By-Hand Approach approach and the pypeit_identify script. Since this spectrograph is decommissioned, we do not expect to have a general solution for this spectrograph.

Object profile

UHRF is a slicer spectrograph, and the data are usually binned aggressively. The object profile tends to be poorly characterised with the automated approach, and you may need to generate your own wavelength dependent profile. Previously, a Gaussian KDE profile was used, and this performed well, but is not available by default. For users that are interested in this functionality, please contact the PypeIt developers on the PypeIt User’s Slack, or see the aat_uhrf_rjc branch.
