This MR add two new lines for B^+ \to K^+ \pi^0 and B^+ \to \pi^+ \pi^0 decays with \pi^0 \to e^+ e^- \gamma, based on the experience of reconstructing D^+ \to \pi^+ \pi^0 decays in the Charm group. We've seen that the yield per inv fb increased by a factor of 10 between Run2 and Run3 for \pi^0 \to e^+ e^- \gamma decays, therefore it might now be worth including this final state for the B^+ \to h^+ \pi^0 decays. The yield will be small due to the low efficiency, but the sample would be softer than the calorimeter \pi^0 approach.
The lines has been run over all events in the sprucing testing snippet and the bandwidth is as follows:
| Line | Eff | Rate |
|---|---|---|
| BuToKpPi0_Dalitz | 2/371018 = 0.0000054 | 0.41 Hz |
| BuToPipPi0_Dalitz | 3/371018 = 0.0000081 | 0.61 Hz |
file_size = 171k
b/w (GB/s) = input rate (75.49 kHz for this HLT2 output file) x 0.171 (MB) / 371018
b/w (GB/s) = 0.000035 GB/s = 35 (KB/s)
