TESS sectors 55 and 82 give consistent half-depth transit widths for MASCARA-1 b

We tested whether the transit profile of MASCARA-1 b changed between two TESS visits in 2022 and 2024. We fitted separate spline profiles to 8 and 9 transits in sectors 55 and 82. The profiles include the effect of the exposure time. The intrinsic half-depth widths are 225.72 and 225.83 minutes. The measured change, sector 82 minus sector 55, is +0.11 minute. The middle 95% of 400 whole-transit refits spans -0.52 to +0.77 minute. The 20-second data give a change of +0.19 minute. Other flux and fit controls also give small changes. Synthetic three-minute changes are recovered on the observed timestamps. We find no resolved width change under these tests. The error ranges hold errors shared by a sector fixed. The result measures a brightness profile. It does not measure an orbit change. The package includes the four source FITS files, code, hashes, per-draw widths, and figures.
