Introduction

THIS PACKAGE IS COMPLETELY DEPRECATED ***

The DetectorStatus package implements a service to manage detector status information, primarily to flag events where some or all subdetectors are unusable, or should be used with caution. The service maintains a DetStatusMap object, which consists of pairs of string identifiers and associated DetStatus objects. These contain an integer code (mapping to the traffic light colours: 1=red, 2=yellow, 3=green), plus floats specifying the fraction of dead modules and the thrust of the dead modules (giving an idea of their concentration). The DetStatus and DetStatusMap objects are defined elsewhere in the DetDescrConditons data objects package.

For more details on detector status handling, see the CoolDetStatus wiki page at https://twiki.cern.ch/twiki/bin/view/Atlas/CoolDetStatus

Flags and conditions DB storage

Each DetStatus object has a corresponding string identifier, which is stored in COOL as the name of a COOL channel in the detector status folder. The currently defined list of COOL channels and string identifier names is as follows:

For each COOL channel, the COOL payload consists of three items: the integer 'Code' which gives the status, the float 'deadFrac' giving the fraction of dead modules, and the float 'Thrust' giving the thrust value of the dead modules. The bottom two bits of the Code variable define the colour (unknown=0, red=1, yellow=2, green=3), and the other bits are free for the user (e.g. to indicate more details of the type of failure).

Detector status information is stored in the COOL conditions database in the /GLOBAL/DETSTATUS/LBSUMM folder, indexed by luminosity blocks. The LBSUMM folder in the OFLP200 database contains a default set of entries valid for all runs, given GREEN status for all detectors with zero dead fraction, tagged with the COOL tag DetStatusLBSumm_nominal. Entering the status for a particular run will then override this default information.
