Smoother spectral degradation about coronagraph HOT 2 CLOSED

Thanks @hippke – This is a great point! The jitter seen in the last figure in that example (pasted below) does indeed come from the naive/non-optimal placement of the grid:

By default, the photon count rate calculation determines the wavelength grid from the min and max wavelengths (Telescope.lammin and Telescope.lammax) and the spectral resolving power (Telescope.resolution) that the user provides. However, the user can optionally provide the wavelength and delta-wavelength grids by setting Telescope.lam and Telescope.dlam before performing the noise calculations.

Within this simpler example, you are absolutely right, the optimal grid placement and average albedo could be found by iterating the minimum wavelength over a grid that spans the width of the wavelength interval at the oxygen A-band. Then the optimal grid solution could be manually passed into subsequent S/N calculations, using the method I described above.

I would be happy to add this calculation and discussion to this example if you think others would find it useful!

Just to follow up on this, I updated this example in the docs to address this comment. The bottom line is that the above curve can indeed be smoothed by optimizing the placement of the wavelength grid:

Thanks @hippke for pointing this out!
