Algorithms Overview

This page contains detailed information about the algorithms used to process the imaging and spectroscopic data used in SDSS, SDSS-III and SDSS-IV.


Important considerations that affect all forms of SDSS data


Software to view and process SDSS data

Target Selection

Algorithms that define how various spectroscopic programs of the SDSS select objects for spectroscopic follow-up

Infrared Spectroscopy

Algorithms that process SDSS-III APOGEE infrared spectroscopic data and associated catalogs

Integral-Field Spectroscopy

Algorithms that process SDSS-IV MaNGA optical integral-field spectroscopy

Interferometry Spectroscopy

A beginners guide to MARVELS data and a description of pipeline algorithms.
