Quick summary of observations per day
Mon, Jan 20
First light. Check detector noise. Test main scripts to be used: track, cross, pointliss, focusp, focusliss, otfgeom, skydip_up, skydip_updown.
- Radio alignment by background minimization.
- No antenna data for the entire session.
Tue, Jan 21
- Investigation on the Nasmyth offsets: understand how the telescope Nasmyth reference coordinates are projected on the array.
- Investigation on the alignment: RADIO ALIGNMENT BY BACKGROUND MINIMIZATION DOESN'T WORK; using the laser alignment give stronger signals; the background minimization is probably due to vignetting of the pupil by the sky next to M2.
Statistics on pointing corrections, pointing at a source for 1 hour. test script otf10x10. 2 beam maps.
Wed, Jan 22
- Iterations on focus scans to check focus variability.
- 1 beam map. Additional tests on Nasmyth offsets.
Use bad weather condition to test acquisition procedures and data with polarizer components: 1st modulator on, no half-wave plate, then with HWP immobile, then rotating. Try optimization of polarizer angle. Test scripts otf5x5, otf5x5_pol, otf5x5_half.
Last test with Nasmyth offset, choose 'reference detector: 494 on the 2mm array.
- Secondary calibrator: W3OH.
