Default use Calibration Kit "open", adjusted Multi SFP crate default parameters, stripped result-file output

added calc_sfp_timing_cal_mod.py which calculates the SFP Timing Calibration parameters form the AnalyzeScopeData.py correlation stat_result.txt files

added measurement result to be plotted in "fiber Delay Coefficient (alpha) as a function of wavelength". Greek characters

avoid warning "Covariance of the parameters could not be estimated" by changing curve_fit method to 'trf'

removed linear fit and 1st order approximation from "CRTT versus wavelength figure" and "fiber Delay Coefficient (alpha) as a function of wavelength"

	sw/insitu_alpha/analyze_sellmeier.py

Added Sellmeier_fitted_crtt_for_first_ITU_channel to result.txt to see CRTT vs temperature variation

added Sellmeier fits in one plot.
