This archive contains time-resolved spectra of the planetary transits for V1298 Tau b andHIP67522 b, accounting for the presence of unocculted spots. These spectra were computed usingthe model presented in Petralia et al. (2025) and the stellar parameters specified in Axis A.1. Forthe planetary transmission component, the mod2_pt2 model was employed (see ExoCASH:Models, Spectra & Simulations for further details).Technical Specifications:• Wavelength range: 0.45 to 8 micron;• Spectral resolution: R3000, Super-sampled by a factor of 3;• Temporal coverage: Simulations span 2.5 times the transit duration, centered at the firstmid-transit time of the TESS sector analyzed in Axis A.1. The spot configuration isconsistent with the photometric analysis of that sector;A README.txt file provides instructions on how to access and read the two spectral data files:• V1298taub.npz• HIP67522b.npz
