Based on the Spextool [2] IDL package (version 4.1 [3]), a new suite of data reduction algorithms, specifically designed for the data format and characteristics of ARCoIRIS, has been written by Dr. Katelyn Allers [4] (Bucknell University). Telluric correction and flux calibration of the post-extraction spectra are achieved through the xtellcorr [5] IDL package. The ARCoIRIS adaption of the Spextool package can be downloaded here [6].
Videos describing how to use the Spextool IDL program for ARCoIRIS can be found here [7].
