HMI_IQUV_averaging - derive Stokes vector I,Q,U, and V observables

Synopsis
HMI_IQUV_averaging begin= end= wavelength= quicklook= camid= cadence= lev1= npol= size= average= rotational= linearity=
HMI_IQUV_averaging creates 12-min or 96-min averaged Stokes vector I,Q,U, and V observables (WARNING: the output series names are built-in and the program should not be run without editing and recompiling except for production). The code outputs are level 1.5 DRMS records: Stokes vector I, Q, U, and V. The code produces these records for all the slotted times in the time interval provided by the user. HMI_IQUV_averaging can produce definitive or quick-look (near-real time, nrt) observables.

Depending on the values of the command-line arguments, the outputs of HMI_observables are put in different DRMS series. When the average is 12 minutes: For IQUV observables obtained from definitive level 1 records and from a standard observable sequence with a 135s cadence, the output DRMS series is hmi.S_720s. For IQUV observables obtained from quicklook/nrt level 1 records, the series is hmi.S_720s_nrt. When the average is 96 minutes (WARNING: THIS IS NOT A STANDARD OBSERVABLES PRODUCT, AND NO NRT SERIES IS CURRENTLY AVAILABLE): For IQUV observables obtained from definitive level 1 records and from a standard observable sequence with a 135s cadence, the output DRMS series is hmi.S_5760s.

Under normal operations, for the 12-min average, other DRMS modules (HMI_observables, hmi_segment_module and hmi_patch_module) using the output of HMI_IQUV_averaging are run immediately after completion of HMI_IQUV_averaging: for production these two modules should always be called after.
