Minimize Level-1 Wave SLC Products

WV acquisitions consist of several vignettes, with each vignette processed as a separate image. Thus, each WV product contains multiple images, all corresponding to the single-polarisation in which the data has been acquired (VV or HH). As the SM SLC product, the WV SLC product is sampled at the natural pixel spacing.

The following properties are particular to each beam of the WV mode.
