Spitzer Photometry of WISE-Selected Brown Dwarf and Hyper-Luminous Infrared Galaxy Candidates [PDF]
, 2012 We present Spitzer 3.6 and 4.5 $\mu$m photometry and positions for a sample of 1510 brown dwarf candidates identified by the WISE all-sky survey. Of these, 166 have been spectroscopically classified as objects with spectral types M(1), L(7), T(146), and ...

Luminosity and photometry [PDF]
Proceedings of the Royal Society of London, 1897 The luminosity of the spectrum was determined by what may be term ed the method of the “minimal effective stimulus.” Through the partition separating two dark rooms from each other a hole was drilled 1 mm. across; this was covered with a piece of ground glass.

Variable Stars in the Globular Cluster M5. Application of the Image Subtraction Method [PDF]
, 1999 We present $V$-band light curves of 61 variables from the core of the globular cluster M5 obtained using a newly developed image subtraction method (ISM). Four of these variables were previously unknown.

Improved GALEX UV Photometry for 700,000 SDSS Galaxies [PDF]
arXiv, 2023 The Galaxy Evolution Explorer (GALEX) satellite performed the first and only large-area UV survey, which in tandem with the Sloan Digital Sky Survey (SDSS) has facilitated modeling of the spectral energy distributions (SEDs) of low-redshift galaxies and the determination of various galaxy properties, in particular the star formation rate.
