Data reduction scripts for RSS alignment testing

Installation Instructions

The following scripts require these packages to be installed in order to run. These can all be installed via pip or conda:

• numpy
• scipy
• matplotlib
• astropy
• ccdproc
• astroscrappy
• pyspectrorgaph
• pyqt

At this time, the development versions of these two packages need to be installed

• specreduce

The specreduce does depend on PyQt4 package.

Suggested method for installing most of the necessary packages via anaconda

conda create --name aries -y python=2.7 astropy pyqt matplotlib 
source activate aries
conda install -c astropy ccdproc specutils
pip install pyspectrograph 
git clone https://github.com/crawfordsm/specreduce
cd specreduce
python setup.py develop
cd 
git clone https://github.com/crawfordsm/salt_aries

Instructions

To perform basic data reductions, follow these steps:

Run the basic reductions on the data.

Pass the name of the file to aries_basic_reductions.py to reduce each file. There are in addition several optional flags that can be passed to remove a bias, for example.

python aries_basic_reductions.py [files to be reduced] 

Create wave maps for each of the arc frames

python aries_measure_arc.py [arc file]

Produced difference spectra

python aries_difference_spectra.py [reference file] [comparison file] --yc [y-center] --dy [radius]
