The IGRINS PLP is designed to produce decent quality of processed data of all the observing data without (or minimum) human interaction. It was also designed to be adaptable for a real time processing during the observing run.
The key concept of this pipeline is having a "recipe" to process a certain data group. These approach is utilized by many other observatories/instruments. In most cases, the recipe needs to be set and recorded in the header (or log) when the observation is executed. Unfortunately, this is not properly done. Therefore, to run the pipeline, you should have an input file describing which recipe should be used to which data sets.
IGRINS pipeline package is currently in active development. Version 3 is the latest version and is recommended for use for reducing data from the McDonald 2.7m, LDT/DCT, and Gemini-South telescopes. Version 2 will still work for those who need it. Version 1, that was originally developed by Prof. Soojong Pak's team at Kyung Hee University (KHU), is deprecated and is not recommended to use. Versions 2-3 were developed by the pipeline team at KASI (led by Dr. Jae-Joon Lee) in close collaboration with KHU's team. Additional development and testing for v3 has been carried out by Kyle Kaplan and Erica Sawczynec at the University of Texas at Austin Department of Astronomy.
IGRINS data is made publically availiable through the The Raw & Reduced IGRINS Spectral Archive (RRISA). The current version of RRISA (v1) uses the IGRINS PLP v2 for it's data reductions. The raw data are also availiable for RRISA for those who want to perform their own data reduction with the IGRINGS PLP.
The version 1 pipeline is described in the following publication.
