Data Reduction Frequently Asked Questions
Are there any colour transformations available for the ISAAC filters and another filter system?
Coccato et al. (Msgr, in preparation) computed color transformation between ISAAC and VIRCAM filters. Using the known color conversion between VIRCAM and 2MASS (http://www.eso.org/sci/data-processing/faq.html#vircam), it is possible to derive the following transformations between ISAAC and 2MASS photometric system:
Js_ISAAC = 0.941 * J_2MASS + 0.059 * H_2MASS + 0.144
H_ISAAC = 0.976 * H_2MASS + 0.024 * J_2MASS + 0.057
Ks_ISAAC = 0.998 * Ks_2MASS + 0.002 * J_2MASS + 0.036
