== HMI Pipeline Module - TimeAverage_IQUV == For a given time and duration this pipeline module locates the corrected level 1 HMI filtergrams needed to compute I, Q, U, and V. The filtergrams are interpolated to the proper time, remapped to the correct disk coordinates, and averaged to determine I,Q,U,& V. The output is a DRMS dataset containing the appropriately time-averaged quantities corrected for solar rotation and other known instrumental effects. ===== Module Inputs ===== . Input is the set of corrected level 1.0 HMI filtergrams needed to compute I, Q, U, and V for a specified time period. ===== Module Outputs ===== . The output is a DRMS dataset containing the appropriately time-averaged quantities I, Q, U,and V, corrected for solar rotation and other known instrumental effects. ===== Cadence ===== . Nominally 12 minute averages of I,Q,U, and V will be produced. . Effectively 8 90-second input records will be averaged, but actually more will contribute with appropriate weighting to reduce aliasing. ===== Options ===== . Anti-aliasing option . Time and duration of averaging ===== Archive ===== . I,Q,U, and V are not archived. ===== Overall Status of Module ===== . 75% complete ===== Status of Code ===== . 85% . Code has been run on HMI test data ===== Status of DRMS module ===== . 50% ===== Issues needing resolution ===== * Type of temporal anti-alias temporal filtering ===== Responsible scientist ===== .
