The following pages contain information which may be stored in the Status Server. Wherever possible, access rates, datatypes, and sizes have been identified.
# Status Server database
# ----------------------
#
# Format is /path/and/varname = # Description in comment
#
# Formatting of <sample value> indicates "native" type for this field.
# This is handled internally by the routine that serializes the database.
#
# TRUE/FALSE - Booleans will have *un-quoted* TRUE or FALSE as the value.
# "string" - Strings always saved with " as the first char in value field.
# 10. - Float values will always show a decimal point (even if .0)
# 15 - Numeric values without a decimal indicate integers.
#
# Top-level "directories":
#
# /i/ with a subdirectory for each instrument (often same names as handlers)
# /t/ with subdirectories for each telescope subsystem
# /p/ for plant environment, weather, data-logger variables
# /q/ for information associated with queue observing
# /f/ has subdirectories for each exposure where FITS headers are accumulated
