Tianlai Analysis Teleconference

US/Central
Peter Timbie, Peter Timbie (UW-Madison)

Minutes

Not much was said about summer meeting.  Haijun Tian just emphasized that he needed to send a list of foreign participants (speakers and non-speakers) to the government before much else could be done.   This I believe includes advertising the meeting e.g. a poster and a “public" website.  The list doesn’t need to be complete (or accurate?).
 
Jixia talked about observation plans
1) there is a broken optical fiber which can not easily be fixed during the winter since it is underground.  They have identified a temporary workaround which should fix the problem until Spring thaw.
2) there is a new GPU correlator.  Priority is to commission it on the cylinder array.  Retuning to a higher frequency band (lo-z) won’t take place until ~July.  
 
Shifan gave a nice presentation on the coupling paper - draft can be found here

An online LaTeX editor that’s easy to use. No installation, real-time collaboration, version control, hundreds of LaTeX templates, and more.

Kaifeng Yu also gave a really nice presentation on map making comparing various regularization techniques.
 
No-one volunteered regarding arXiv papers. 
 
Future meetings:    Greg and Peter have teaching conflicts on Tuesday.   Poll suggests Mondays might work?
 
The Chinese New Year begins February 9 - after the next meeting.  So we should have a meeting in two weeks and need to determine when that is.
