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 NOAO Science Archive.
Newly updated (v2.2, May 2015), the NOAO Data Handbook now includes:
New documentation on the COSMOS (CTIO) and KOSMOS (KPNO) instruments. Intended as a guide to data reduction and calibration for PIs and Archive users of data from NOAO’s twin multi-object imaging spectrographs.
Help for finding and downloading data from observations made with NOAO facilities.
Help for finding and downloading NOAO Survey Data
February 2015: Reduced data products from the Dark Energy Survey (DES) Year 1 data release are now available in the NOAO Science Archive. The data release consists of a large number of DECam images in several sky areas, individually reduced and calibrated (photometrically and astrometrically) by the DES science team. The DES-Y1 Release Notes describe these data products in detail. The NOAO Science Archive Simple Query Form now includes buttons that simplify searches for both raw and reduced DES images.
Table detailing the NOAO DECam pipeline versiona dn the associated Community pipeline versions from DESDM. Includes the date the pipeline was deployed and the changes in the version.
A guide to file names in the NOAO archive, addressing both raw and pipeline-reduced data products.
IRAF documentation includes manuals for the IRAF language as well as cookbooks and manuals for both generic data reduction and specific NOAO instruments.
Iraf.net provides information and support from the IRAF Development Group, including a user forum, IRAF documentation and user guides, and FAQ pages.
Pipeline documentation provides information about the design, performance, and use of the data reduction pipelines that have been produced for instruments on NOAO telescopes.
FPACK - Instructions for the FPACK routines used for compressing and uncompressing FITS data stored in the NOAO Science Archive.
