ABSTRACT:General expressions are developed for the statistical errors to be expected in photometric measurements due to confusion in a background of
fluctuating surface brightness.
Backgrounds actually observed in the far IR by
the IRAS satellite are used to calculate tables of these error expressions
for two simple measurement techniques.
The confusion-noise-limited
sensitivities for NASA's planned Space IR Telescope Facility and the ESA's IR Space
Observatory are estimated at a wavelength of 100 microns from these tables.
