      Description

      AL decorrelation when pre-convolution is enabled has similar issues to those described in DM-11993, but more frequent. Also results in the noise of the decorrelated, pre-convolved diffim being extremely inaccurate (too high). Probably also due to similar causes which are exacerbated by the inclusion of a noisy PSF in the decorrelation kernel term.

            The decorrelation afterburner code was since re-implemented. A similar and now well understood issue is DM-25050.
