Offline 70um filtering of photometry observations with IDL

For photometry observations of a single source, we suggest using the following two procedures for cleaning up artifacts at 70 um. The IDL tools assume access to the IDL astrolib.

(1) bcd_column_fiter.pro

  • Calculates the median value for each column.
  • Subtracts value for each column for each BCD.
  • Updates the bcds in input list.
(2) bcd_time_filter.pro

  • Calculates median for each pixel for the data set to derive pixel-to-pixel additive correction (ignoring source and bad pixels). The procedure derives a one correction for the entire input data set (only one time correction). If used for a large data set, you may want to divide the data up into multiple sets in time order.
  • Subtracts value from each pixel for each BCD.
  • Updates the bcds in input list.
