NIKA2 technical run #67 / August 2024

Back to the NIKA2 Run 67 main page

Goal

Carry out verification tests of the 30 m telescope using NIKA2, after recoating of M1

Essential issues to be tested:

* Check the feasibility and correctness of NIKA2 observations in a first approach after the last stop

* Test day/night behaviour of the beams

* Photometry and RMS check using flux calibrators

Observations required:

* Standard day/night point & focus sequences

* A good statistics of calibration scans on selected planets and secondary flux calibrators (see visibility plot)

* Night-time beam maps (~30 min each); possible targets to be used: 2251+158, Uranus, 0316+413

* A new lateral focus session would be necessary (stable conditions, telescope relaxed; it takes about 3h)
