Magnitude And Color Transformations Between Sirius And 2Mass Photometric Systems
Author
Summary, in English
We provide magnitude and color transformations between two near-infrared photometric systems, 2MASS and SIRIUS, the latter currently implemented with the three-Channel SIRIUS camera on 1.4 m Infrared Survey Facility telescope at the South African Astronomical Observatory. The transformation equations are derived using a carefully selected sample of 32 770 stars in the. Large and Small Magellanic Clouds that have high quality observations available in both photometric systems. The derived transformations are valid in the color range -0.1 < (J - H)(SIRIUS) < 1.15, -0.05 < (H - K-s)(SIRIUS) < 0.7 and -0.1 < (J - K-s)(SIRIUS) < 1.7.
