Description
We report on the sensitivity of SPIRE photometers on the Herschel Space
Observatory. Specifically, we measure the confusion noise from
observations taken during the science demonstration phase of the
Herschel Multi-tiered Extragalactic Survey. Confusion noise is defined
to be the spatial variation of the sky intensity in the limit of
infinite integration time, and is found to be consistent among the
different fields in our survey at the level of 5.8, 6.3 and 6.8 mJy/beam
at 250, 350 and 500 μm, respectively. These results, together with
the measured instrument noise, may be used to estimate the integration
time required for confusion limited maps, and provide a noise estimate
for maps obtained by SPIRE.
Herschel is an ESA space observatory with science instruments provided
by European-led Principal Investigator consortia and with important
participation from NASA.
