Description (last modified by curtis)

We collect a system response file that represents the instrument's behavior when no excitation takes place. This file should be used to adjust the lifetime histograms (via deconvolution) to improve the quality of the fits.

There are actually a total of three types of corrections to do:

  1. The deconvolution for each channel's lifetime histogram.
  2. A deskew of the spectral channel delays based on values in the calibration file.
  3. A scaling factor to apply to each spectral channel, to adjust for an "intensity skew" across channels.

The system response file will contain all of this information, once the engineers figure out the most reliable way to collect it.

Replying to curtis:

Ticket #135 has more details on the spectral calibration issue.

Also, the current plan is to embed relevant calibration information into each dataset, rather than have separate calibration files, to ensure the correct calibration is always available; see ticket #183.

Be sure to check out the  Parallel Spectral Deconvolution 2D and 3D plugin for ImageJ, as it may be relevant.
