MAPS Jun. 2025A Night 4: RM modes

Tonight was another beautiful clear night. Seeing ranged from around 1-3 arcseconds. At the start of the night we were confused why we were seeing very little AO correction — it turns out the TT mirror was not modulating, oops! After this we took several sets of AO-on vs. AO-off Pisces data. We also compared the response matrix modes for a set of 20-modes-RM taken with 5 trials and it is encouraging that we are seeing the Zernike-ish modes as expected!

The song of the night is “Num Num Cat TikTok Chain but its actually good lol”:
