Dear all, We have a response to our (Nikhef) comments. I will look at it tomorrow.

Re: [Bfys-physics] LHCB-PAPER-2015-053-001-COMMENT-012 (a comment has been made on your comment)
by Mick Mulder 12 Jan '16

Dear all, The proponents have responded to our comments on PAPER-2015-053. They can be found at https://cds.cern.ch/record/2116308. Please take a look and see whether your comments were adequately adressed. Personally, I think most of their response is good, but I am not satisfied with their answers to our questions on fixing most of their fit shapes and determining a systematic uncertainty for their fit model. They do not answer the question on fixing their shapes, and on the topic of determining the systematic uncertainties they only discuss why they choose now to vary their shapes to estimate fit model uncertainties, and ignore the topic of possible toy studies. What do you think we should do about this?

Dear all, Due to the glorious fact that I made another integer amount of loops around the sun, there will be cake in the coffee corner at 15:00. Hope to see you there! If not, no problem. More for the rest! Cheers, Jacco
