The naming convention for MAVEN CKs is as follows:
 
   mvn_STR_TYPE_YYMMDD_yymmdd[OPT]_vVV.bc
 
where
 
   STR  – structure for which orientation is given:
             sc -- spacecraft CKs
             app -- APP CKs
             swea -- SWEA boom CKs
 
   TYPE – type of orientation:
             nom -- nominal data
             pred -- predicted data
             rec -- reconstructed data, generated after DSN passes
             red -- reconstructed data, generated daily
             rel -- reconstructed data, generated weekly
 
   YYMMDD -- coverage start date
 
   yymmdd -- coverage stop date, omitted for daily files
 
   [OPT]  -- optional tokens

   VV     -- version
 
---
 
All three strings of reconstructed CKs ("rec", "red", "rel") are generated from
 the same attitude telemetry.
 
The "rec" files are generated soon after DSN passes, have uneven coverage
 and occasional gaps.
 
The daily "red" files are generated daily and are re-made multiple times on
subsequent days to "catch up" on any data that may have been downlinked
with a delay.
 
The weekly "rel" files are generated weekly, first with a week delay and then
 again with a three week delay to ensure that no data downlinked very late
 have been missed.
 
In summary, "rel" files are best and should be used for all time periods for
which they are available.
 
The "red" files should be used for more recent days, for which weekly files
are not yet available, and should be abandoned in favor of weekly files when 
weekly files become available.
 
The "rec" files should be used only when neither "red" not "rel" files are 
available, i.e. for most recent past before "red" and "rel" files become 
available.
 
Predicted CKs should be used only for the future and for periods for which 
reconstructed files have irrecoverable gaps and s/c is know to follow 
planned attitude profile.
 
In general, the loading order for MAVEN CKs should be
 
   pred    (lowest priority)
   rec
   red
   rel     (highest priority)
 
For all CK types, the file with the latest version supersedes all previous 
versions.
