Abstract

Data reduction techniques have been implemented recently to obtain infrared spectra of astronomical objects from raw data obtained with the mosaic detector array and prism slit spectrometer used for groundbased telescope astronomical observations. During the course of the analysis, several instrumental peculiarities presented significant complications that were ultimately addressed. The techniques for flat fielding a slit spectrometer cannot follow exactly those used for an imaging camera, but a limited flat fielding approach can be used in conjunction with measurements of known calibration sources to calibrate the entire array. The end product described here allows a pipeline application of computer software to raw data frames that results in astronomical spectra independent of atmospheric and instrumental attenuation.
