FTS Simulation Datasets

Data used in the paper "The Atacama Cosmology Telescope: Passband Measurements with an Analysis of Systematic Errors." The datasets are (1) `shift_attr_data_20260226_monte_carlo_5x5.h5`: Data from the optical simulation of the FTS which can generate the frequency shift and FTS transfer function plots found in the work (2) `corrections_unnormalized.dat`: Data from the simulation of the beamsplitter in HFSS at both 0.08 and 0.025mm thickness (3) `lowband_forwards_sim_transmission.csv` and `highband_forwards_sim_transmission.csv`: Data from the HFSS SBR+ simulation of the coupling optics lens transmission. The two simulations use different paramidal horn input antenna dimensions to span a combined larger frequency range.
