DESCRIPTION:

The BLST files (one per bundle) provide a list of SFMP files needed to tie together frame overlaps within the bundle (core frame vs core frame) as well as with adjacent bundles (core frame vs edge frame).  In addition the SFMP files contain 2MRef position data need to symmultaneously tie to the reference stars.  By setting up the BLST files to point to SFMP files with 2MRef modified using proper motions from UCAC4, proper motions which occured between the 2MASS and WISE epochs are accounted for.  BLST files contain one record per frame with each frame degisnated as "core" or "edge".  The "core" frame belong uniquely to the bundle and the "edge" frames while they overlap "core" frames belong to adjacent bundles. In order to conserve resources, not all possible "edge" frames are included.  MFPRex has the ability to further reduce the edge frames actually used via random selection. BLST file names encode the bundle ID in the first field of the name.  Such as:

BID01890-BLST.tbl

\
\ COLUMN HEADER DESCRIPTIONS:
\ type      = Frame type (core=in-bundle; edge=adjacent-bundle)
\ bndlID    = ID of bundle for which this frame is "core"
\ SFMP      = Full-path name of SFMP for frame
\ score     = QA score assigned to frame
\ JDf       = Julian date of frame (day)
\ sdir      = Scan direction of frame (ASC or DES)
