JHK INFRARED STANDARD STARS AND ABSOLUTE CALIBRATION OF THE SAN PEDRO MARTIR OBSERVATORY (OAN) PHOTOMETRIC SYSTEM

A set of reliable standard stars for the JHK photometric system of the San Pedro Mártir National Observatory (OAN) is presented. Mean extinction coefficients for the near IR of this site are first reported here; effective wavelengths and flux calibration from observations of Vega are derived for the...

Description
Summary:A set of reliable standard stars for the JHK photometric system of the San Pedro Mártir National Observatory (OAN) is presented. Mean extinction coefficients for the near IR of this site are first reported here; effective wavelengths and flux calibration from observations of Vega are derived for the various bandpasses. Comparison with other widely used photometric systems is presented and, finally, transformation equations to CIT, AAO, ESO, and Johnson's systems are derived.
