Instrument and chlorophyll-filtered sunlight interferograms. The raw instrument-filtered interferogram was recorded on August 23rd, 2019, at 11:36 and the raw chlorophyll-filtered interferogram was recorded on September 18th, 2020, at 12:54. All interferograms were recorded in Edinburgh, Scotland between August 2019 and September 2020. (a,b) both show well defined centre bursts and strong symmetry around the ZPD due to successful phase correction using the Forman method. The interferogram in (b) shows more prominent sidelobe oscillations compared to (a) due to the additional filtering by the chlorophyll analogous filter package. Raw data for each phase corrected interferogram can be seen in the respective inset. The complex degree of temporal coherence components of (c,d) have lower resolution compared to the phase corrected interferograms of (a,b), respectively, due to the method by which the \(\gamma (t)\) is extracted from the single-beam spectrum.
