Alessandro 22h45. I stop the turbo for the weekend. Plan to switch it ON on Monday in the late evening. Alessia, could you put the NIKA2 window back in place so we can check the noise between Monday and Tuesday ? Good night ! |
Back to the NIKA2 run 10 main page
April, 18th (Tuesday)
Start of the official run.
April, 14th (Friday)
Alessia at the telescope and Juan remotely.
We started doing two dark scans. We tried to point using 3C84 but the source was far from the center -38,-20 arcsec. After discussions with Juan Peñalver we decided to use nasmyth offset computed by Nicolas on run 9: offsets -18.8 -5 /sys nasmyth, However, this did not solve either the problem. We switched to Mars but encountered the same problem. Finally, we found that the problem was related to a wrong reference kidpar - we corrected this and everything started work fine. However the weather during the day was very unstable although tau was not that bad: about 0.3-0.4 from IRAM taumeter. We have performed a small pointing session to verify the current model. We tried to get some Mars beammaps after focus X,Y, Z. We did a couple of skydips. Finally, we tried to go to PSZ2G144.85 to do a first test but had no enough time. Really a pity because the weather improved quite a lot.
