Tianlai Analysis Teleconference

Minutes

 

1.  Low-z paper almost published:  https://academic.oup.com/mnras/advance-article/doi/10.1093/mnras/stac2832/6754328?utm_source=authortollfreelink&utm_campaign=mnras&utm_medium=email&guestAccessKey=21a2a0d5-04d3-4146-ae29-d572874008b5

2.  Software & Data Management - Reza

We need a system similar to Tianlai01 which is more accessible to team members outside Fermilab.   At UW?  Brown?   Albert could provide a (100 TB?) disk array.  Fermilab also has old disks from business section that might be available.

3. WIYN/Hydra proposal.  We were not awarded time in the current semester (2022B): 

"We had a very high oversubscription rate this spring, and 3 of the people applying were thesis students.  We always give thesis students priority assuming they've written a solid proposal.   I think we opted to give your proposal no time, since it had visibility both semesters.  (In the end it didn't matter much -- the fire on Kitt Peak this summer clobbered everyone's time.   They are still not back to normal operations yet.)

 

If you re-apply, the key thing would be to demonstrate why it's essential to the science to observe your last few fields.  While completion is nice, it's not often strictly necessary to get a paper out.    I rather suspect we'll be oversubscribed again since people lost most of their time this semester, but we'll have to see."

4. Strange transient events seen in cylinder data on Monday while Sun below horizon.   Zijie and Furen showed waterfall plots (attached below).  Not seen in dish data.   Solar activity?

5. Olivier is looking at dish observations of bright sources from 2017 and 2018.   'Ripples' in gain vs frequency plot appear in 2017 but not in 2018.  Jixia thinks there may have been a problem with the correlator.

 

6.  Topics for future weeks?  Albert has an idea to present next week.
