input: Write a function to perform a series of calculations and generate plots based on input data. The main function should load the input data, perform calibration using functions from eval_spectrum.py and calibration.py, calculate various power values, and generate plots for absorbed power vs emitted power, absorbed power vs reflectivity, and dissipated power vs wavelength. The function should also calculate thermal resistance and display it on the plot. The function should take a logfile and a calibration folder as input parameters. Return True if the calculations and plots are successfully generated, otherwise return False. If the logfile or calibration folder is empty, return False.
