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, `~pyhrs.HRSOrder`, that includes position, wavelength, and flux properties
+ A class describing the HRS spectrograph, `~pyhrs.HRSModel`, to allow for accurate modeling of the HRS Spectrograph
+ Raw data can be processed using `~pyhrs.hrsprocess` for both the blue and red arms.   
+ Orders can be identified in the images using `~pyhrs.create_orderframe`
+ `~pyhrs.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.
