The NOIRLab Data Handbook: A guide to accessing and using data from major NOAO instruments. The Data Handbook describes the formats and characteristics of raw data, and the pipeline processing applied to all recent and current observations and its data products. It also describes how to access these data in the NOIRLab Science Archive. this version includes:

  • Introduction to NOIRLab data: holdings, formats, the NOIRLab Science Archive, data use policies
  • Mosaic cameras
  • NEWFIRM infrared imager
  • Dark Energy Camera
  • C/KOSMOS spectrographs

NOIRLab File-naming conventions: A guide to file names in the NOIRLab archive, addressing both raw and pipeline-reduced data products.
