Mimir data reduction and analysis tools:
Current Available and Supported:
1. Mimir Software Package - Basic Data Processor (MSP-BDP) - a GUI-based IDL "project" that will allow performing all the raw data intake, quality testing, bookkeeping, dark/flat/linearity corrections needed to generate "science ready" images.
2. Mimir Software Package - Spectroscopy Data Reduction Tools - with Cookbook
Wavelength Calibration Tool (MSP-WCT) - a GUI-based IDL "project" that will aid the user in performing wavelength calibration of Mimir spectral images, using either OH night sky lines or images taken of the Argon line lamp. Will produce linearly dispersed, slit-shape corrected spectral images suitable for spectrum extraction.
Clean and Coadd Spectral images (MSP-CCS) - designed to take A-B dithered spectral images from the WCT and optimally stack, filter, and sum them. Produces the best S/N from Mimir spectra. Output goes to the spectral extractor (SXC).
Spectral Extractor and Converter (MSP-SXC) - extracts stellar or extended spectra from spectral images. Package also supports conversion from SpeX-type FITS files to ASCII, baseline removal from spectra, parsing into photometric bands, and plotting with line ID overlays for a variety of stellar types and emission line objects. No GUI as of yet.
Baseline Removal Tool (MSP-BRT) - for removing baselines, chopping spectra, etc.
Spectra Combining Tool (MSP-SCT) - for putting chopped spectra back together. Allows offsetting
Spectrum Annotation/Analysis Tool (MSP-SAT) - for displaying spectra, marking key lines and features. Includes H, He recomb. lines, most neutral atomic lines, ionic lines, molecular lines. Permits redshifting, zooming, and output to Postscript files.
3. Mimir Software Package - Photo-Polarimetry Analysis Tool (MSP-PPOL) - a GUI-based IDL "project" to perform astrometry, scaling, coadding, calibration, PSF-assisted crowded field aperture photometry, and polarimetric analysis of GPIPS-like polarimetry data from Mimir. Produces image tiles, PHOTCAT deep photometry (tied to 2MASS H-band magnitudes), and POLCAT polarizations for stars.
4. Mimir Software Testing Packages - for uncovering problems and quality assurance for polarimetry observations and data reductions
A. Zero Hop Tester (MSP-ZHT) - a GUI-based IDL project for testing Mimir polarization images for the presence of problems with HWP rotation ('zero hops' refer to problems in setting the HWP to zero phase). May be run on raw (CDS) images or images at any stage of processing. Also works on flat-field images.
B. EB Detector (MSP-EBD) - examines POLCATs to look for unphysical patterns, usually due to HWP hiccups.
C. Mock Star Tool - creates mock stars with real image PSFs, scales them to match magnitude distributions, inserts them into Mimir images, recovers results from MSP-PPOL Step 8 and 9 processing, and analyzes recovery rates, completeness, false positives, and Stokes U,Q properties. Currently a work in progress for a draft paper.
Note: Users must also fetch the "Astrolib_MSP" and "MSP_Library" zip files - the first is an older 'frozen' version of astrolib that was used when developing the Mimir Software Packages. (newer astrolibs will not work)
Internal Group-Level Tools:
5. Mimir Software Package - Data Release Manager (MSP-DRM) - early version of package to manage moving PPOL-processed GPIPS fields to the data-release 'candidates' disk file system. Not needed by general Mimir or GPIPS users.
6. Mimir Software Package - Mosaicking and Overlay Tool (MSP-MOT) - a GUI-based IDL "project" to stitch together GPIPS images and POLCATS into larger mosaicked images with polarization vector overlays (saves as FITS and/or TIFF files).
To fetch the S/W
Astrolib_MSP - 20140325 - the frozen version of astrolib needed by the packages below
MSP_Library - 20140707 - local library of routines shared by the packages
Mimir Software Package - Basic Data Processor (MSP-BDP), v3.4.3 - 20161206 (supports COADDS image types)
Mimir Software Package - Photo-Polarimetry Analysis Tool (MSP-PPOL), v8.4.3 - 20170221 - fixed PSF normalization problem and resolve_underscores crashes. v8.4.2 added support for mock star experiments and protection for saving Group Summary sav files (solves a remote file mount problem).

At present, no packages have documentation or adequate help files. On the other hand, they have been written so that the processing steps, once completed, direct you to the next step.
