Finally good measurements of zero and high-polarization standard stars were obtained in J and H in September to access the current polarimetry mode of NOTCam that consist of a set of 4 Polaroids, but the data still need to be reduced and analyzed. Specifically, the quick-look reduction tool for polarization observations still needs some improvements.

It is evident that an upgrade to a dual-beam polarimeter would be the way to go for NOTCam polarimetry (at least for point-like sources), but a full study still needs to be completed.
