Flux values being updated for cryogenic IRAC 5.8 and 8.0 micron data
14 Mar 2012
We are currently updating the fluxes and header
information about flux conversion in all cryogenic
IRAC channel 3 and 4 SHA data. We will remove this message
once all the fluxes have been updated. Please investigate
the headers of the downloaded IRAC channel 3 and 4 files
to see what the processing version is (check the CREATOR
keyword near the top of the header). If it is S18.25,
then the new flux calibration has been applied. If it is
S18.18, then the old flux calibration has been applied.
Channel 1 and 2 flux values will remain the same, but
the pipeline processing version will be updated to S18.25.
