Apply a matched filter defined by the image model available in file ImageData (default extension .lmv-clean) to the UV data set available in file UVData (default extension .uvt), and save the filtered result into files Result.uvt and Result.dat. Continuum emission is automatically removed using UV_BASELINE, with line windows defined by UV_PREVIEW.
If argument Result is not present, the intermediate files are stored in gag_scratch::detect.uvt and gag_scratch:detect.dat
