HRS Data Reduction (pyhrs)

Introduction

Note

pyhrs works only with astropy version 1.0.0 or later. It also requires ccdproc version 0.3.0 or later.

The pyhrs package provides steps for reducing and extracting data from the High Resolution Spectrograph on the Southern African Large Telescope. The package includes the following sub-packages to help with the processing and reduction of the data:

• A class describing a single HRS order, HRSOrder, that includes position, wavelength, and flux properties
• A class describing the HRS spectrograph, HRSModel, to allow for accurate modeling of the HRS Spectrograph
• Raw data can be processed using hrsprocess for both the blue and red arms.
• Orders can be identified in the images using create_orderframe
• wavelength_calibrate_arc can be used to calculate the wavelength calibration.

Once the data are reduced and calibrated, extraction of the object spectra can proceed based on the prefered method of the user.
