Data Set Overview
===================
This dataset contains status data generated by the BOPPS Infra-Red Camera (BIRC)
during flight. 

The data are separated into three types:

Pointing Data - consisting of ASCII fixed-width tables that contain the pointing
information generated by the gondola and sent to the BIRC instrument to be
stored and downloaded

Temperature Data - consisting of ASCII fixed-width tables that contain temperature
values reported by sensors in the BIRC instrument. These have been converted from
DN to engineering values.

Relay Data - consisting of ASCII fixed-width tables that contain information on 
various relay states and the cryo-cooler pressure.

Processing
==========
Temperature and relay data were generated at a set rate of 0.1Hz. Pointing data 
was generated at a rate of 20Hz. During flight a subset of the pointing, relay,
and temperature data were downloaded along with the images in binary compressed
telemetry files. This was done to enable the SOC to perform shift and coadd
operations in near real time. In addition, a full set of status data was stored
on-board the BIRC instrument in ASCII files and downloaded post flight to the SOC.
An algorithm was applied to the ASCII files to convert them from DN to physical
units. The data were then collated into groups of records representing 1 hour's
worth of data and written to fixed-width ASCII tables along with an associated
PDS4 XML label.

Data
====

	Each status product is stored in ASCII fixed-width table format.
	Any associated metadata is contained in the XML PDS label associated with the
	ASCII table file.
	
	File Naming Convention
	----------------------
    The file naming convention for the Status data products in this collection is:
    
	yyyy_mmdd_hhmmss_obsd_t.ext
	
	where:
	
	yyyy_mmdd– four digit year, two digit month, two digit day of month corresponding
	to the timetag of the first record converted to UTC

	hhmmss – two digit hour, two digit minute, two digit second corresponding 
	to the timetag of the first record converted to UTC

	obsd – 4 character string identifying the type of observation. See table 5 in the SIS
	for a short description of each of the observation types identified.

	t – single character indicating the product type:
     r – RELAYS
     t – TEMPERATURE
     p – POINTING

	.ext is a three character file extension. Either ‘tab’ for the ASCII table
	file or ‘xml’ for the PDS4 XML label.

	File Organization
	-----------------
	Due to the relatively small number of files for each product type, the files
	are organized into product type folders which contain all files
	generated for the specific product type.
