Transit light curves of K2-25 b taken with MuSCAT2 & 3 in 𝑔, 𝑟, 𝑖, 𝑧-band (from top to bottom) on each observing night. 𝑁T number is shown next to each light curve. In each subplot, observed data points are shown in grey points, and best-fit transit + baseline models derived by GP regression are indicated in coloured lines. The shaded regions indicate the 1𝜎 error of the GP model. -- astro-ph.EP

Characterization of Starspots on a Young M-dwarf K2-25: Multi-band Observations of Stellar Photometric Variability and Planetary Transits
