摘要：

An absolute calibration of the DENIS photometric system is presented. It includes the determination of the overall transmission. profiles in the 3 bands, namely i, J and K(s), combining contributions from atmosphere, telescope mirrors, instrument lenses and dichroics, filters: and detectors. From these normalized profiles, isophotal and effective wavelengths are computed, using the same synthetic Vega spectrum as that used to support the absolute calibration of many other ground-based and spaceborne photometric systems. Flux densities at zero magnitude are derived and integrated to give in-band fluxes, which are used to compute theoretical zero-points and compare them to observed ones, yielding estimates of the overall throughput of the whole system.
