| During maintenance, the new make-imbf is transformed into the default one. From now on we will use only the new make-imbf and the old one will be kept inactive. We verify that the directory where the make-imbf wrote is not the "production" directory and that all users can read its content. We also run the PIIC QL manually on a couple of old scans, of which William newly produces the files using the new make-imbf and writing them here. The QL reads and processes these scans regurlarly.

Preliminary plan
We wish to do the following:
- start in total power: point, focus (!), point, calib_1scan, beam maps (at least 2)
- analyze focus difference between Ar1 and Ar2
- analyze beam maps and produce DAFs RPPs for the new Ar3. Install the new RPPs for Ar3
- analyze the focus difference between Ar1 and Ar3
- perform many focus sequences to have some statistics
- polarimetry beam maps
- more total power beam maps
- out of focus total power beam maps
- total power deep field (HLS 091828), to derive the new, final NEFD of NIKA2 TP
- polarimetry deep field (3C286, M87, 3C353, ...?) to derive the new IQU NEFD of NIKA2-Pol
- 084-25 polarimetry
- 140-25, 146-25 polarimetry
- 196-25 total power
- test long subscans with our favorite, total power, 100 arcsec/s
- C/2025 R3 Panstarrs, polarimetry
- deep field 03h32m31.75s −27d46m51.5s, total power, 14x14 arcmin2, 100 arcsec/s
- test Sgr A* polarimetry scan strategy
- ... other wishes ...

The team arrives safely to the observatory 
we are all thrilled and super excited to test and use the new NIKA2++!
During maintenance, the new make-imbf is transformed into the default one. From now on we will use only the new make-imbf and the old one will be kept inactive. We verify that the directory where the make-imbf wrote is now the "production" directory and that users can read its content. We also run the PIIC QL manually on a couple of old scans, of which William newly produces the files using the new make-imbf and writing them here. The QL reads and processes these scans regurlarly. Well done!
We take over after maintenance at 14:45 UT. All is ready. We start with total power (TP). And we stop at scan nr zero, because we are in the clouds and the humidity is at 100%. The rain alarm rings loud!
Progress of the day:
