In rev. 7648, some fields in the CbmStsCluster and CbmStsHit data classes were deprecated:
1) CbmStsCluster->Mean was replaced by CbmStsCluster->Center
2) CbmStsCluster->MeanError was partially replaced by CbmStsCluster->channelMeanSq
3) CbmStsHit->SectorNb was fully deprecated

I made some adaptation to use the new fields and allow compilation and a behavior as close as possible to original.
However I had to use fix errors in StsCosyClusterFinder and to use unused data field for the detector ID in CbmStsHit, so this need to be checked and done in a better way.

The changes were commited to trunk by Florian in rev. 7819.

An accessor to "fChannelMeanSq" in CbmStsCluster would allow to get back the original error calculation method.

The other "hack" is that I used the frontDigiId field in CbmStsHit to store the station index instead of the deprecated SectorNb. Here I am not sure that a modificationto the data class would improve anything.

Actions #4

  • Status changed from Assigned to Resolved
  • % Done changed from 50 to 100

Modifications done in rev. 8294. Issue resolved, can be closed after somebody checks with a COSY file that results are now identical to old behavior.

  • Status changed from Resolved to Closed

Anna did her own modifications in her not yet committed version of the COSY unpacker. Eventually the changes done for this issue will need to be also done in her version, an email with a link to this issue was sent to her.
