Data Reduction Frequently Asked Questions
Are there any colour transformations available for the SOFI filters and another filter system?
Kurtev et al. 2007, A&A, 475, 209 computed the color transformation between the following SOFI filters and the 2MASS photometric system:
Ks_SOFI = 0.996 * Ks_2MASS + 0.004 * J_2MASS
J_SOFI = 0.995 * J_2MASS + 0.005 * Ks_2MASS
H_SOFI = H_2MASS + 0.021 * (J_2MASS − K_2MASS)
