Module Override for Robustness studies:


Works via producing a map of disabled modules, which gets written into a conditions database override, which can then be read in by jobs.

- Production of the overlay map is done by specifying the identifiers of the modules to be masked in PixMapOverlayWriter. Code changes needed to read in the identifiers (unsigned int -> unsigned long long) but the mechanism for overriding actually uses the ID hash, not the identifier for the most part. This means that a truncated, 32-bit integer can be written in to the std::map of (Hash,ID) which is written to the DB folder. The only bad effect this has, is that the ID is used to check the range when applying the module overlay map, so some changes are needed to get around this in SpecialPixelMapSvc.

- Once the DB override is produced, it can be applied during reconstruction by using the usual method for overriding conditions folders. The relevant folder is PixMapOverlay


Provide a list of Identifiers for modules to be vetoed directly in an options file, using the SCT_ModuleVetoSvc

- Minimal code changes needed - only one change in SCT_ModuleVetoSvc.cxx, where a string conversion to int instead of a long long is used.

- Python changes in InDetRecExample needed, adding the SCTModuleVetoSvc to the list of algorithms run by the ConditionsSummarySvc, and also allowing it to run for SLHC (conditions access usually switched off for such cases)


Packages that need to be checked out and modified are:

- InDetRecExample

- PixelCalibAlgs

- PixelConditionsServices

- SCT_ConditionsServices

The changed .cxx and .h files are located in /afs/ along with some example options and .db files


This looks a bit suspicious:

As does this hard coding on number of chips:
