Four-color and HP photometry has been obtained for 16 stars in the open cluster NGC 6087. Based on this photometry the membership of these stars in the cluster is discussed. Using stars which appear to be members a color excess of E (b y) = 0Y23 and a distance modulus of (V, M,) = 9%0 are derived. This distance modulus is about 0% less than previous values and indicates a lower luminosity for t...

IES LM-79-08: IES Approved Method for the Electrical and Photometric Measurements of Solid-State Lighting Products. Describes the method of absolute photometry for LED luminaires and integral replacement lamps, and associated electrical measurements. Provides performance data (i.e., light output and efficacy, light distribution, and color characteristics) for the entire, integrated product—vers...

We present optical and near-infrared photometry of 45 clusters of galaxies at 0.1 < z < 1.3. Galaxy catalogs in each cluster were defined at the longest wavelenth available, generally the K-band, down to approximately two magnitudes below M∗. We include finding chart images of the band used for catalog definition. The photometry has been used in previously published papers to examine the origin...
