0001 //

0002 //  SiPixelTemplate2D.cc  Version 2.65

0003 //

0004 //  Full 2-D templates for cluster splitting, simulated cluster reweighting, and improved cluster probability

0005 //

0006 // Created by Morris Swartz on 12/01/09.

0007 // 2009 __TheJohnsHopkinsUniversity__.

0008 //

0009 // V1.01 - fix qavg_ filling

0010 // V1.02 - Add locBz to test if FPix use is out of range

0011 // V1.03 - Fix edge checking on final template to increase template size and to properly truncate cluster

0012 // v2.00 - Major changes to accommodate 2D reconstruction

0013 // v2.10 - Change chi2 and error scaling information to work with partially reconstructed clusters

0014 // v2.20 - Add cluster charge probability information, side loading for template generation

0015 // v2.21 - Double derivative interval [improves fit convergence]

0016 // v2.25 - Resize template store to accommodate FPix Templates

0017 // v2.30 - Fix bug found by P. Shuetze that compromises sqlite file loading

0018 // v2.35 - Add directory path selection to the ascii pushfile method

0019 // v2.50 - Change template storage to dynamically allocated 2D arrays of SiPixelTemplateEntry2D structs

0020 // v2.51 - Ensure that the derivative arrays are correctly zeroed between calls

0021 // v2.52 - Improve cosmetics for increased style points from judges

0022 // v2.60 - Fix FPix multiframe lookup problem [takes +-cotalpha and +-cotbeta]

0023 // v2.61a - Code 2.60 fix correctly

0024 // v2.65 - change double pixel flags to work with new shifted reco code definition

0025 //
