Faint Standards for UKIDSS and VISTA ZYJHK
The currently defined 'United Kingdom Infrared Telescope (UKIRT) Faint Standards' have JHK magnitudes between 10 and 15, with K_median_=11.2. These stars will be too bright for... -
Main sequence intrinsic colours: O8V to M0V
A new Monte Carlo method has been developed in order to derive ages of young embedded clusters in massive star-forming regions where there is strong differential reddening.... -
Secondary standard stars in u'g'r'i'z'
We present a new set of secondary standard stars for the u'g'r'i'z' photometric system that has been established in selected open and globular star clusters. These standards are... -
Faint photometric BVR CCD sequences
CCD photometric standard stars in the BVRc system of Johnson and Cousins are presented for two regions of importance in studies of galactic structure and kinematics: the North... -
uvby-beta CCD photometry secondary standard
Accurate standard uvby indices are presented for 73 southern B, A, F and G stars in the V magnitude range 8.2 to 10.9. They cover all three transformation regions of the uvby... -
SN 2007on and SN 2011iv light curves
We present an analysis of ultraviolet (UV) to near-infrared observations of the fast-declining Type Ia supernovae (SNe Ia) 2007on and 2011iv, hosted by the Fornax cluster member... -
Photometric standards around gravitational lenses
We present a catalog of secondary photometric standard stars in the neighborhood of 14 gravitationally lensed quasars. These stars were verified to be non variable using... -
Standard magnitudes in the E regions
A single table combines the revised and extended results of 24 series of photometric observations made in South Africa between 1947 and 1960 on the nine Harvard E regions at... -
Photometric Standard Stars
CCD photometry is presented for 119 stars observed in the Thuan-Gunn photometric system (the passbands vgr). The sample includes 82 stars for which magnitudes in this system... -
NIR K-corrections
Type Ia Supernovae (SNe Ia) have been used as standardizable candles in the optical wavelengths to measure distances with an accuracy of ~7% out to redshift z~1.5. There is...
