Data reduction scripts for RSS alignment testing

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

To perform basic data reductions, follow these steps:

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] 

python aries_measure_arc.py [arc file]

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