Meeting Notes
Present: Ashlea Kemp, Joe Bayley, Elena Cukanovaite, David Hadden, Professor Boogert, Professor Cowan
- Make sure to include some mathematics onto twiki i.e. the functions that were plotted to graphs, explain each parameter
- Make sure to include numerical values onto twiki (values for mean positions, etc)
- Check
value - should not be that small!

- Want to find wavelength as a function of pixel position along x axis and micrometer setting, i.e.
- Fit one peak at a time in each frame, and find 3 parameters for each spectral lines: mean position
, its corresponding wavelength
and micrometer setting
. Once complete for whole spectrum, try and fit function
for data. Find
for functional fit to help determine the best functional fit i.e. linear, quadratic etc.
- Origin of increasing background from left - right: at one side of CCD, there is some electronics generating heat and noise, hence there is some unavoidable rising background due the way camera is built. Can take Bias frame with 0 exposure to explore this
- Normalise values to pixel per second exposure time.
- Algorithm to search for hot pixels: for 1D, want to look at some derivative change.
