TL;DR: In this article, a polynomial model for estimating the metallicity and rotational velocity distributions of SDSS spectra was proposed, which is similar to random and systematic uncertainties in spectroscopic determinations.

TL;DR: In this paper, the authors model the time variability of ~9000 spectroscopically confirmed quasars in SDSS Stripe 82 as a damped random walk (DRW) and find that τ increases with increasing wavelength with a power-law index of 0.21 ± 0.07.

Stellar SEDs from 0.3-2.5 Microns: Tracing the Stellar Locus and Searching for Color Outliers in SDSS and 2MASS

TL;DR: In this paper, an algorithm was developed to calculate a point source's minimum separation from the stellar locus in a seven-dimensional color space, and use it to robustly identify objects with unusual colors, as well as spurious SDSS/2MASS matches.
