Halogen Lamp

• Use the better fit for calibration of the wavelength and see how plot turns out

Mapping

• The larger standard deviation of the residual plot could be a underestimation of error bar or an incorrect form of the equation
• Make the bins of histogram smaller
• Put each histogram on same plot
• For estimating values use ( ) and (), where ar values at the middle fo the surface.
• Start the next function from these values and set new parameters to zero.
• Plot a series of individual plots instead of residuals

Error estimation

• Take multiple frames of the line, take more at each exposure, note down cooler temp etc
• mark the line that is being monitered, put bands on the plot e.g where the mean is and the Poisson error band comapred to the measured.
• With the different exposures space logarithmically.

Line Fit

• Put all of the fits onto one plot to see how they vary
• Sort out the skewed Gaussian convolution
