Association Blocks

An Association Block (AB) contains for a set of raw frames all information about associated other files. The most important pieces of information are:

all input raw frames
associated other raw frames (like ACQUISITION frames associated to SCIENCE frames)
associated calibration products

It also hosts information about pipeline reduction (recipe name, parameters for execution).

The AB is meant to be machine readable. A short form, focusing on the associated calibration products only, is the association log. It is more easily readable by humans.

The syntax of an AB consists of a qualifier (the name of a parameter) and its content:

- The first column has the name of the qualifier.
- The other columns have the content.
- Any text behind a # is considered a comment.

All path information in an AB has been valid during the workflow and is obsolete for the package which has a different structure.

For the user of a data package, only those qualifiers are of potential interest which are marked by 'user'. All others are technical qualifiers which can be ignored.

Qualifier	Relevance for the SM user	description
TOOL_VERSION		version of tool which created the AB
CONFIG_VERSION		version of configuration file used

INSTRUMENT		read from the input files
DATE	user	date of raw data

DPR_CATG	user	value of DPR.CATG of first input raw file
RAW_TYPE		technical type
RECIPE	user	pipeline recipe name
DRS_TYPE		type of data reduction system (RBS/CPL/REI)
PACK_DIR	user	name of subdirectory for packing of calibration data

AB_NAME	user	name of AB
AB_EVENT		technical grouping rule
COMPLETENESS	user	completeness status (COMPLETE/INCOMPLETE)
PROCESS_STATUS	user	CREATED/SUCCESSFUL/FAILED

OBS_PROG_ID	user	value of OBS.PROG.ID
OBS_ID	user	value of OBS.ID

MJD-OBS		value of MJD-OBS (start of integration)
MJD-OBS_MOD		calculated from MJD-OBS+EXPTIME/2 (MJD-OBS of middle integration; used for time matching)

PROD_ROOT_NAME		root name of products

RB_NAME		name of Reduction Block (DRS_TYPE = RBS only)
LOG_NAME	user	name of processing log

# pipeline product path
PROD_PATH		full path name to products

# raw match key
RAW_MATCH_KEY		set of specific keys (name=value) used to group the raw input files

# input file(s)
RAWFILE	user	column 2: full pathname of input file; column 3: DO_CLASS (used by the pipeline)

# associated raw file(s) (only for SCIENCE; taken from same night only!)
RASSOC	user	full pathname of associated raw files (e.g. ACQUISITION frames; SCIENCE only);

# product file(s) (with status in calib archive)
PRODUCTS	user	column 2: final name of product file(s) of this AB
PRODUCTS		column 3: name of archived file(s)

# calib product file(s), required for processing
MCALIB	user	associated master calibration data, needed for processing
MCALIB		column 2: type (REAL or VIRTUAL); VIRTUAL stands for predicted product names, REAL for existing ones
MCALIB		column 3: full pathname to product
MCALIB		column 4: PRO_CATG of product
MCALIB		column 5: associated AB of that product (pointing to the associated calib raw files)

# addional calib product file(s), used for packing (SCIENCE only)
MASSOC	user	full pathname to further calibration products required for packing

# parameters for processing
PARAM	user	name and value of non-default parameter(s) required to execute the recipe

# defined triggers (for REI)
TRIGGER		information for batch queue system

# defined waitfors (for REI)
WAITFOR		information for batch queue system

# associated QC1 parameters stored in QC1 database:
QC1_DB		name of QC1 database table which has QC1 parameters from this AB

# further associated information:
FURTHER_...	user	name(s) of associated further information (e.g. QC1 plots)

# status of AB
AB_STATUS	user	messages about creation, execution, update of this AB

# ============== RB section starts here ============================ (only until April 2008)

RB_CONTENT (only until April 2008)		full Reduction Block content extracted from this AB (for better human readibility)

# ============== SOF section starts here ============================

SOF_CONTENT		full SOF (set of frames) file content extracted from this AB (for better readibility)
