UBVRI Photometric Standard Stars Around the Sky at -50 Degrees Declination
Arlo U. Landolt
UBVRI photoelectric observations have been made of 109 stars around the sky, centered more or less at -50 degrees declination. The majority of the stars fall in the magnitude range…
Optical Multicolor Photometry of Spectrophotometric Standard Stars
Arlo U. Landolt, Alan K. Uomoto
Photoelectric data on the Johnson-Kron-Cousins UBVRI broadband photometric system are provided for a set of stars which have been used as spectrophotometric standard stars at the H…
Multi-Color Photometry of the 2001 Superoutburst of WZ sagittae
Steve B. Howell, Arne A. Hendon, Arlo U. Landolt
We present the results of U-band and multi-color photometry during the 2001 superoutburst of WZ Sagittae. Our 10 nights of U-band photometry span the time interval from HJD 2452118…
A Quantitative Comparison of SMC, LMC, and Milky Way UV to NIR Extinction Curves
Karl D. Gordon, Geoffrey C. Clayton, K. A. Misselt +2
We present an exhaustive, quantitative comparison of all of the known extinction curves in the Small and Large Magellanic Clouds (SMC and LMC) with our understanding of the general…
Optical and Infrared Photometry of the Nearby Type Ia Supernova 2001el
Kevin Krisciunas, Nicholas B. Suntzeff, Pablo Candia +8
We present well sampled optical (UBVRI) and infrared (JHK) light curves of the nearby (~18.0 Mpc) Type Ia supernova SN 2001el, from 11 days before to 142 days after the time of B-b…
Starcounts Redivivus: III. A Possible Detection of the Sagittarius Dwarf Spheroidal Galaxy at b=-40
S. R. Majewski, M. H. Siegel, W. E. Kunkel +5
As part of the Selected Areas Starcount Survey (SASS), a CCD survey to V>21, we have obtained VI photometry of two fields at b=+-40 aligned roughly with an extrapolation of the maj…
