It requires yearly image collections of `timeSeries` (containing specific bands) and `landCover` to produce a per-pixel 2D array. This array contains information for each year, including the VCT landcover mask, and the magnitude of disturbances based on UD composite, B4, NDVI, and dNBR. VCT's function can be customized by using arguments like `maxUd`, `minNdvi`, `forThrMax`, and `nYears`.\n"]]
