-==== Effelsberg pulsar observers meeting ==== 
- 
-Meeting in E1.08 on 26 Sep 2018, 13-14:00 hrs 
- 
-Attending: Michael, David, Gregory, Henning, Kuo, Ramesh 
- 
-A not-so-complete list of improvements 
- 
-  - Meta data on PSRIX (ROACH1) data products. Receiver, BW are not correctly recorded. Solution is to move to PSRFITS where some of the parameters can be set correctly.  
-  - PSRFITS issues on beegfs. To check with Willem for a possible solution. 
-  - ROACH2 output has no proper header information - source/position etc. - fix this 
-  - Possibility to control the instruments via Obsinp. 
-  - Telescope data from multicast/broadcast? Put data in to a shared memory, so others can take look. 
-      - broadcast may disappear in 2-3 yrs, and multicast is the way to go. In 2-3 yrs when control system is replaced 
-      - The broadcast stream has incorrect data when the "new control system" is used. 
-      - Check if multicast has sensible data. The multicast stream is not really in the spirit of a XML structure. 
-  - 10dB gain slope across the C+ bands - saturates parts of the spectrum and under-samples the higher end 
-     - to be addressed in the attenuation/gain unit (proposal/requirements with Gundolf). 
-  - ROACH2 w/iADC and ROACH1 to operate in parallel 
-  - Check ROACH2 w/ interleaved ADCs if performance has improved with new chassis and calibration 
-  - Check ROACH2 w/ ADC in non-interleaved mode and compare with ROACH1 (after chassis modification) 
-      - To test all four cores of the ADC to verify the performances of the cores
