Abstract
We describe the current state of the ground segment of Herschel-SPIRE photometer data processing, approximately one year into the mission. The SPIRE photometer operates in two modes: scan mapping and chopped point source photometry. For each mode, the basic analysis pipeline - which follows in reverse the effects from the incidence of light on the telescope to the storage of samples from the detector electronics - is essentially the same as described pre-launch. However, the calibration parameters and detailed numerical algorithms have advanced due to the availability of commissioning and early science observations, resulting in reliable pipelines which produce accurate and sensitive photometry and maps at 250, 350, and 500 ?m with minimal residual artifacts. We discuss some detailed aspects of the pipelines on the topics of: detection of cosmic ray glitches, linearization of detector response, correction for focal plane temperature drift, subtraction of detector baselines (offsets), absolute calibration, and basic map making. Several of these topics are still under study with the promise of future enhancements to the pipelines.
