Yield differences between analysis ver05, ver08, ver12 (workfest): analysis meeting May 30, 2018

Update email from June 5, 2018: 

Hi Sean,

sorry it took me so long to get back to you. Here are the numbers and files for the main peak only.

Number of combos in ver05 2153
Number of combos in ver08 1602
Number of combos in ver12 2062
Number of combos only in ver05 1206
Number of combos only in ver08 616
Number of combos only in ver12 1394
Number of combos in ver05+ver08+ver12 321
Number of combos in ver05+ver08 793
Number of combos only in ver05+ver08 472
Number of combos in ver05+ver12 475
Number of combos only in ver05+ver12 154
Number of combos in ver08+ver12 514
Number of combos only in ver08+ver12 193

Cross-checks:
only in ver05 + ver05+ver08+ver12 + only in ver05+ver08 + only in ver05+ver12 =  2153
only in ver08 + ver05+ver08+ver12 + only in ver05+ver08 + only in ver08+ver12 =  1602
only in ver12 + ver05+ver08+ver12 + only in ver05+ver12 + only in ver08+ver12 =  2062
