1. Data Levels

   RPS data is delievered in 5 levels
     * Level 0 - raw instrument packet data
       [35]rbspa_L0-2c1-rh_psbr-rps_20121001_v3.0.0.cdf or
       [36]rbspa_L0-2c2-de_psbr-rps_20121001_v3.0.0.cdf
          + Time is expressed in Mission Elapsed Time (MET) not UTC
               o MET is approximately seconds since 00:00 UTC on 1 Jan
                 2010
               o Each file contains one mission day (not exactly a UTC
                 day) approximated by the UTC day of the file name in
                 YYYYMMD format (older versions of filenames used the
                 4-digit mission day)
               o Mission Day 1 is 30 Aug 2012
          + Files with APID 2c1 are 1-second rate and housekeeping data
            ([37]metadata)
          + Files with APID 2c2 are direct event data, at most one packet
            per second, potentially multiple events per packet
            ([38]metadata)
     * Level 1 - Conversion to physical units
       [39]rbspa_L1_psbr-rps_20121001_v3.0.0.cdf [40]metadata
          + Each file is one UTC day, given in YYYYMMDD format in the file
            name
          + Contains 1-second rate and housekeeping data (depends on
            Epoch)
          + Contains 1-second rates in each data channel (approximately an
            energy/species channel)
          + Contains high rate event data (depends on EVENT_Epoch and
            variables with names EVENT_*)
          + Contains estimated energy and other event characteristics
     * Level 2 - Flux versus energy versus time, two file types
          + Each file is one UTC day, given in YYYYMMDD format in the file
            name
          + Spin sectored files:
            ([41]rbspa_L2_psbr-rps_20121001_v3.0.0.cdf [42]metadata)
               o 73 time bins per vehicle rotation
               o Also contains event data in EVENT_* variables carried
                 over from level 1 files
          + One-minute average files
            ([43]rbspa_L2-1min_psbr-rps_20121001_v3.0.0.cdf [44]metadata)
     * Level 3 - Flux versus energy and pitch angle versus time
       [45]rbspa_L3_psbr-rps_20121001_v3.0.0.cdf [46]metadata
          + Each file is one UTC day, given in YYYYMMDD format in the file
            name
          + Contains multiple flux vs angle for different coordinate angle
            coordinates (E.g., spin sector, local pitch angle, equatorial
            pitch angle)
          + One minute averages in each angle bin
     * Level 4 - Flux versus invariants, two file types
          + Each file is one month given as the first of the month in
            YYYYMMDD format in the file name
          + Contains multiple maps for different coordinate systems (e.g.,
            E, K, L* or E, K, hmin, or E, L, ALPHA_EQ)
          + Daily averages in each coordinate bin
            [47]rbspa_L4-byleg_psbr-rps_20121001_v3.0.0.cdf [48]metadata
          + Averages by orbit leg in each coordinate bin
            [49]rbspa_L4_psbr-rps_20121001_v3.0.0.cdf [50]metadata

2. Sensor Response Files

   Sensor response files are also provided [51]README
     * Response to isotropic protons [52]csv
     * Response to isotropic electrons [53]csv
     * Energy-angle response [54]hdf5 [55]cdf

3. Data Versioning

   All RPS data products carry a version number of the form vX.Y.Z.
   Different parts of the version name will be updated depending on what
   has changed:
     * X - The file contents have changed: variables added, deleted,
       renamed, resized, retyped
     * Y - The processing algorithms have changed in a way deemed
       significant
     * Z - New data has been added, minor changes to the processing
       algorithms, changes to the metadata

   All version 0.Y.Z data is preliminary, as it represents an evolving
   data processing system. Prior to version 1.0.0, activities that would
   normally increment the X part of the version number will only increment
   Y. Therefore, level 0.1.Z and 0.2.0 may contain different variables,
   etc, whereas normally such a change would promote version 1.Y.Z to
   version 2.0.0

4. Archive Structure

   For Level 0 data, the ptp file format is the official definitive
   record. For Level 1 and higher products, the CDF file format is the
   official definitive record.

   Also, Level 0 ptp data is not broken out by year, whereas all other
   Level 0 and and higher products are.

   In terms of archiving -- at most only the latest X.Y version of a file
   is retained (e.g., v1.0.1 retained but v1.0.0 deleted). When fluxes are
   not changed, the latest X version may only be retained (e.g., v1.1.0
   retained, but v1.0.0 deleted).
     * [56]doc - documents
          + Metadata -- ASCII CDF Skeleton files
               o [57]Level-0 Rate and Housekeeping
               o [58]Level-0 Direct Event
               o [59]Level-1
               o [60]Level-2
               o [61]Level-2 1-minute
     * [62]rbspa - Data from RPS on RBSP-A
          + [63]rbspa/level0 - Level 0 data for RBSP-A
               o [64]rbspa/level0/cdf - Level 0 data for RBSP-A converted
                 to CDF
                    # [65]rbspa/level0/cdf/2012 - Data for 2012
          + [66]rbspa/level1 - Level 1 data for RBSP-A
               o Same substructure as Level 0
          + [67]rbspa/level2 - Level 2 data for RBSP-A
               o Same substructure as Level 0
     * [68]rbspb - Data from RPS on RBSP-B
          + Same as rbspa folders

5. Release Notes for Level 4 Files

5.1. Version 3.0

     * Initial version and post-mission archive

6. Release Notes for Level 3 Files

6.1. Version 3.0

     * Initial version and post-mission archive

7. Release Notes for Level 2 Files

7.1. Version 3.0

     * Post-mission archive
     * Final corrections to metadata
     * Final temperature and drift corrections applied
     * RPS-A D9 recovery applied
     * Improved total dose and dose rate calculation
     * Updated metadata to improve ISTP compliance

7.2. Version 1.2

     * Correction: seconds with no direct events now have zero flux rather
       than fill
     * Inherited L1 v1.2 timing correction on pitch angle determination
     * On 10 Jan 2018, we began reprocessing all Level 2 (L2) v1.2 files
       to fix the length of the SPIN_OMEGA variable. In earlier v1.2
       files, it had unit length, but in the reprocessed files it has the
       advertised length: the spin rate in rad/s. As this is a change to a
       minor variable, we are not incrementing from v1.2 to v1.3. The
       Level 1 (L1) SPIN_OMEGA variables were correct, and so those files
       are not being reprocessed. This change only affects L2 files.

7.3. Version 1.1

     * Inherited background removal from L1 v1.1: Applied background
       removal for EVENT_DIRECTION=1 and EVENT_TYPE neither PEN(1) or
       CHE(2)

7.4. Version 1.0

     * Changed to byVar compression
     * Minor changes to metadata
     * After the initial v1.0.0 run, a missing factor of 2pi was
       discovered in the PHI (3rd invariant) calculation. That is
       corrected in all files generated after 1/1/2017.
     * Note that After 8 Jan 2016, the RPS-A instrument does not produce
       any fluxes with our current algorithms due to the failure of the
       Cherenkov subsystem. A new algorithm is pending.

7.5. Version 0.5

     * Changed metadata

     * Improved metadata, ISTP compliant

     * Corrected half-second offset in pitch angle interpolation

8.3. Version 1.1
