Abhisek et al.,

We had trouble today with our network in FTBF today, but Martin resolved it this afternoon and we are up-to-date in copying over.

Hopefully, we are updating the elog better now as well, but here is an run index of data taken with the beam so far:

https://www.phenix.bnl.gov/WWW/sPHENIX/haggerty/t1044/2017a/

We're still getting things up to speed, but not a bad haul for the first few days.

If someone points me to web space accessible to sphenix instead of just phenix, we can put this up there.

Abhisek,

There's something funny about copying files to rcf... it looks to me
like we haven't gotten files over there since yesterday, we killed off
all rsync's and we're trying to figure out what's going on.

Hi Edward,
Please be more explicit in the elog about the details on the runs
taken. I started the transfer to RCF. I will have a look once it transfer.

Cheers,
Abhisek

Jin, Sunday is HCAL standalone day. We are planning to take ~500k
events at each of 4 or 5 energies (30/16/8/4 and maybe 2 GeV/c) -
enough data to have ~2k events for every hodoscope crossing. If you
have comments, suggestions - welcomed. Would be great to get some
insight from this data fast.
The first run (30GeV/c mostly negative pions) is 3285.

Hi, Martin and all

Thanks! This flag is very convenient. This switch is incorporated
into a not-yet-merged prototype3 production code:

https://github.com/blackcathj/coresoftware/commit/3236ced2bc2c604a94ab94cd8f3fa9a1daa9259a

Now I will also appreciate if someone could point to me the new HBD
channel map for high-eta EMCal, which will put here:

https://github.com/blackcathj/coresoftware/commit/3236ced2bc2c604a94ab94cd8f3fa9a1daa9259a#diff-4943c7156628a48058c793384d2269b3
