Pointing model is not updated. First pointing try on 1741-038. Only issues at the beginning were related to a bad indent issue in the make_IMBFITS_nika.py code and a high deviation of the source in El. (~80") in the first map. Fixed after repositioning M3 & M4. |

Daily Reports
IRAM staff at Pico:
OoD until Tuesday morning: Gloria Liñan (day), Joaquin Santiago (night)
OoD for the rest of the week: Enrique Lobato (day), Pedro Martinez (night)
Rx & Astro: Dave John, Carlos Duran, Miguel Sanchez, Pablo Torne, Angel Bongiovanni
Relevant hardware conditions at starting:
- An improvement of air pipes, wiring, sensors and control systems of the vertex are being finished by Rx team along this week. Styrofoam membrane has been relocated in standard position before NIKA2 observations. No petals installed yet in the vertex. Some pieces of foam layers need to be replaced between the petals and the styrofoam membrane.
- 15:30 (LT): Last NIKA2 cooling down steps (DJ): turning on amplifiers of 1 mm arrays. No evident PT noise. Bad KIDs (window closed): 16, 1, 25 (ar1, 2, 3)
- 20:20 (LT): Opening NIKA2 window, El. 60 deg. Waiting for a final T_MC stabilization (172 mK). Bad KIDs: 30, 3, 43 (ar1, 2, 3)
