Gunther et al.,
attached is a the upsilon efficiency vs pt for all 3 eta ranges to be used as the right hand side plot in figure 1.4.

I am not sure what is meant by line 124-126. "While these losses are not catastrophic, it is worth noting that within the sPHENIX run plan a 25% loss is equal to the statistics collected in one of the RHIC run periods".

As far as I understand this statement is not correct. The acceptance in PHENIX is about 18 times smaller than sPHENIX so we our stats are much smaller. STAR has a similar acceptance to sPHENIX but readout much slower and limited PiD so I don't think they ever collected upsilon samples in any beam species (pp AuAu) which are 1/4 of the expected sPHENIX stats.

Best regards
Marzia

Friends,

As discussed at the General Meeting today, we are forwarding draft 1 of our
document outlining the detector scope for a $32M cost cap. The pdf file can
be found at

(we'll provide another link tomorrow for those that can't access dropbox)

Please send your comments in reply to this mail, keeping the
[sPH-GEN-2017-002] tag in the subject line***. Comments received by
close-of-business on Monday, 10/23, will be most useful.

Cheers,

***we will move future reviews to an sphenix-notes-l AT bnl.gov list, but the
list couldn't be generated in time for this note.
