FILENAMING CONVENTION
FOR THE
BBSO AND GLOBAL H-ALPHA NETWORK DATA ARCHIVE
================================================================================
In general, BBSO follows the SoHO convention (see below), except that the
observation time will have six characters with format HHMMSS instead of four
characters, and the miscellaneous info code will be modified to represent
different spatial resolution and calibration data.
Example:
1 2 3
012345678901234567890123456789012 <=== character index
bbso_halph_ri_19930820_154122.fts <=== filename
---- ----- -- -------- ------ ---

| | | | Observation time (6 chars, in hhmmss format)
| | | |
| | | Observation date (8 chars, in yyyymmdd format)
| | |
| | Miscellaneous info code (2 chars)
| |
| Image type code (5 chars)
|
Institution code (4 chars)
A standard BBSO file name will consist of 33 characters (including 4
underscore characters and a dot).
