Journal ArticleDOI

The Seventh Data Release of the Sloan Digital Sky Survey

Kevork N. Abazajian, +223 more
TL;DR: A series of improvements to the spectroscopic reductions are described, including better flat fielding and improved wavelength calibration at the blue end, better processing of objects with extremely strong narrow emission lines, and an improved determination of stellar metallicities.
Journal ArticleDOI

Detailed structural decomposition of galaxy images

TL;DR: GALFIT as mentioned in this paper is a two-dimensional fitting algorithm designed to extract structural components from galaxy images, with emphasis on closely modeling light profiles of spatially well-resolved, nearby galaxies observed with the Hubble Space Telescope.
Journal ArticleDOI

CANDELS: The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey

Norman A. Grogin, +108 more
TL;DR: The Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS) as discussed by the authors was designed to document the first third of galactic evolution, from z approx. 8 - 1.5 to test their accuracy as standard candles for cosmology.
Journal ArticleDOI

Detailed Structural Decomposition of Galaxy Images

TL;DR: GALFIT as mentioned in this paper is a 2D fitting algorithm to extract structural components from galaxy images, with emphasis on closely modeling light profiles of spatially well-resolved, nearby galaxies observed with the Hubble Space Telescope.
Journal ArticleDOI

Detailed decomposition of galaxy images. ii. beyond axisymmetric models

TL;DR: GALFIT as discussed by the authors is a 2D fitting algorithm that allows for irregular, curved, logarithmic and power-law spirals, ring, and truncated shapes in otherwise traditional parametric functions.
