input: Write a function to perform a series of calculations and generate plots based on input data from various measurements. The function should first run `eval_spectrum.py` and `calibration.py` with appropriate measurements. The main function should load the input data, perform calibration, calculate various power values, and generate plots showing absorbed power vs emitted power, absorbed power vs reflectivity, and dissipated power vs wavelength. Additionally, the function should calculate thermal resistance and display it on the plot. The script reads plot instructions from a separate text file. If the script runs successfully, it should return True; otherwise, it should return False.
