Photometric standard stars in the field of GR 290
Understanding the origin of the instabilities of LBVs is important for shedding light on the late evolutionary stages of massive stars and on the chemical evolution of galaxies.... -
Spectrophotometric Standards
The catalog contains energy distribution data of 82 stars of 7-8mag belonging to spectral types A0-G2. Spectral energy distribution is presented in the range 3400-7500{AA} with... -
Spectrophotometric Standards
Observers at the National Optical Astronomy Observatories have provided spectrophotometry for 25 stars in the visual magnitude range 7.5 to 16.6. This document describes the... -
Photometric Standard Stars
The non-variable stars brighter than 5.0 mag in the equatorial zone between declinations +10{deg} and -10{deg} were adopted by IAU Commission 25 in 1970 as primary standards for... -
Southern Spectrophotometric Standards. I + II
M. Hamuy, et al. have compiled their observations of secondary and tertiary spectrophotometric standard stars for the southern hemisphere in the wavelength range 3300-7550... -
UBVRI standards around Celestial Equator
The catalog contains UBVRI photoelectric observations of 223 stars, mostly in an approximately 2-degree zone centered on the celestial equator. The catalog is intended to... -
LUT Survey Catalogue Data Release 1
We present an near-ultraviolet star catalogue extracted from the Lunar-based Ultraviolet Telescope (LUT) survey program. LUT's observable sky area is a circular belt around the...
