Processing for the MIPSGAL 24 μm survey of the inner galactic plane
Abstract
We describe improvements to the data processing pipeline for the Spitzer MIPSGAL survey of the Galactic plane. These involve both improvements to the processing of the 24 μm data, in particular the handling of saturations and near-saturated data, and mitigation of various artifacts not corrected in the basic calibration pipeline. The artifacts addressed postpipeline are typically caused by passage across bright point sources very common in the Galactic plane, and include column-to-column "jailbar" striping, latency effects resulting in both short-duration afterimages and long-duration responsivity depressions, scattered light, and background-level mismatches. We describe the artifacts phenomenologically and present in detail the algorithms developed to correct them.
