2 // SiPixelTemplate2D.h (v2.65)
3 //
4 // Full 2-D templates for cluster splitting, simulated cluster reweighting, and improved cluster probability
5 //
6 // Created by Morris Swartz on 12/01/09.
7 // V1.01 - fix qavg_ filling
8 // V1.02 - Add locBz to test if FPix use is out of range
9 // V1.03 - Fix edge checking on final template to increase template size and to properly truncate cluster
10 // v2.00 - Major changes to accommodate 2D reconstruction
11 // v2.10 - Change chi2 and error scaling information to work with partially reconstructed clusters
12 // v2.20 - Add cluster charge probability information, side loading for template generation
13 // v2.21 - Double derivative interval [improves fit convergence]
14 // v2.25 - Resize template store to accommodate FPix Templates
15 // v2.30 - Fix bug found by P. Shuetze that compromises sqlite file loading
16 // v2.35 - Add directory path selection to the ascii pushfile method
17 // v2.50 - Change template storage to dynamically allocated 2D arrays of SiPixelTemplateEntry2D structs
18 // v2.51 - Ensure that the derivative arrays are correctly zeroed between calls
19 // v2.52 - Improve cosmetics for increased style points from judges
20 // v2.60 - Fix FPix multiframe lookup problem [takes +-cotalpha and +-cotbeta]
21 // v2.61a - Code 2.60 fix correctly
22 // v2.65 - change double pixel flags to work with new shifted reco code definition
23 //
24 
25 // Build the template storage structure from several pieces
