We designed the document to serve three purposes:
A significant change from the first version of the NICMOS Instrument Handbook is that the fundamental source of photometric performance is now the NICMOS Exposure Time Calculator (ETC) available on the World Wide Web (see Chapter 6).
Wavelength units in this Handbook are in microns (µm) and fluxes are mainly given in Janskys (Jy).
