Look-up Tables and Software

In this section we provide look-up tables to facilitate rapid, approximate conversion between the different systems mentioned in the preceding section.

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. To carry out some of the conversions described here, simple programs are available on the NICMOS World Wide Web pages at STScI. We are adopting here the CIT system defined in Table 12.2.

By using Table 12.3 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.
