B.3 Look-up Tables
In this section we provide look-up tables to facilitate rapid, approximate conversion between the different systems mentioned in the preceding section. IT is important to note that the precise values will change as the sensitivity of NICMOS continually changes. Users should follow the formulas above to generate their own data while keeping in mind that their calculated values should be close to those provided here.
For both integrated source fluxes and surface brightnesses, we provide tables of conversions between systems at the wavelengths of the four commonly used photometric bands, which cover the NICMOS operating waveband of 0.8–2.5 microns. We are adopting here the CIT system defined in Table B.2.
Using Table B.3, it is possible to estimate the CIT magnitude corresponding to any flux in Jy by using the property that multiplying or dividing the flux by one hundred adds or subtracts five magnitudes.
