<br></div>My initial conclusions:<br><br></div>1. The requirement of having the three (p K+ pi-) tracks in unique sectors is approximately a 1 : 13 effect on the yield and a 1 : 11.4 effect on the flux-corrected yield. The single-sector and production data are consistent with each other to within error which is probably close to +/- 2, so a direct comparison of the two data sets seems reasonable at this point.<br>
<br></div>2. The single/production ratio for the Lambda K+ flux corrected yield is 1.8 +/- 0.7 and I can apply this to the whole production data set, but that still leaves a missing factor of about 2.3 for the low-energy (3-prong trigger) part of the tagger (g12 will be lower than g11a by this factor)<br>
