Discussing the track-fitting quality, chi^2/ndf, vs theta for 2020, compared to the previous running periods. The deterioration for theta>10 deg should be studied with high rate reactions (Alex with rho) or just inclusively (Sean). Alex: many changes have been done in the tracking software for the 2020 production, need to evaluate their effect on the tracking quality.

- GEM-TRD
We finished with the CDC gas tests: no Oxygen at 100ppm level, so CDC is very gas tight. The Oxygen we see with the gas chromatograph most likely comes from the tubing at/around the bubblers. Will restore the gas in the CDC and do the same tests with the FDC. Kondo performed analysis of the resolution of the padGEM (1x1 cm^2 pads) for different pad patterns: found significant improvement (~300 microns) when you have 3x3 pads above threshold.
