Description
The TolTEC camera is a trichroic polarimeter deployed on the 50-meter Large Millimeter Telescope (LMT) on Sierra Negra in Mexico. It observes in three photometric bands 150, 220, and 280 GHz with respective angular resolutions of 10, 6, and 5 arcseconds. TolTEC achieved first light in 2022 and commenced commissioning in December of that year. Issues with the LMT and TolTEC prevented commissioning observations for most of 2023 and 2024 with TolTEC only observing for a few nights. The TolTEC commissioning campaign resumed in January 2025.
We present an update on TolTEC commissioning with results from after December 2022. This update includes a discussion of techniques used to improve the gain of the TolTEC and LMT optical system, and preliminary images taken a degree-scale region in the Serpens South star cluster and other fields.
