MEDS ready to implement as well, have tried it out with the beta file. Basic way I'm grabbing the appropriate slope (in python, assuming grabbing nearest defined slope is the appropriate method?):

import pandas as pd

def get_rt_slope(lat, lon):
    slope = pd.read_csv(resource_path('SLOPE_RT_2024.txt'), sep=' ')
    index = ((slope.lon - lon)**2 + (slope.lat - lat)**2).idxmin()
    
    return slope.loc[index].slope
