E614 will also adopt the Calibration File Manager (CFM) developed for BNL experiment E787. CFM allows the user to associate run numbers with calibration files. Calibration types (plane position corrections, wire position corrections, etc.) may be defined through CFM. For example, DC_PPC defines the calibration type for the Drift Chamber Plane Position Corrections. CFM allows up to 5 characters to identify a component (Drift Chamber, DC, in this case) and up to 3 characters to identify its attributes (Plane Position Corrections, PPC). The file name for a calibration type has the form XXXXX_YYY.NNNNN where NNNNN is a 5-digit (version) number called an indicator. For example DC_PPC.00001 is a PPC file name with indicator number equal to 1. CFM is then asked to associate a run number, or a group of runs with indicator 1 for the calibration type DC_PPC. When MOFIA is run it checks the run number and obtains the indicator number and the file name for each calibration type from CFM. CFM expects all calibration files to reside in the directory defined by the environment variable CAL_DB. To run CFM type CFM (outside MOFIA). Commands may be issued at the CFM command line to view the contents of CFM or modify and change the existing information. The help command provides the user with online help. For a more detailed description of CFM, please refer to the E787 document by Morgan Burke.
Several calibration files have been defined in CFM for
use with MOFIA 2.0, and are listed below:
Type Number | Type | Description |
1: | DC_PPC | Drift chamber UV plane position corrections |
2: | DC_WPC | Drift chamber UV wire position corrections |
3: | DC_RES | Drift chamber resolution parameters |
4: | DC_PRC | Drift chamber plane rotation corrections |
5: | DT_GEO | Detector Geometry |
6: | FBC1_MAP | Mapping file for first FASTBUS crate |
7: | FBC2_MAP | Mapping file for second FASTBUS crate |
8: | FBC3_MAP | Mapping file for third FASTBUS crate |
9: | DC_PZC | Drift chamber plane Z position corrections |
10: | DC_WZC | Drift chamber wire Z position corrections |
11: | DC_WRC | Drift chamber wire rotation corrections |
