Cumulative coarse image cubes & Basic & 34 TB &  Coarse spectral image cubes with 14 spectral channels in Stokes I, Q, U and uncertainty in I and Q/U (accumulated). \textbf{For the BDP this requires compression/reduction to 10\% of full volume. These are cutouts around 1e6 sources or less.}.\\  Cumulative fine image cubes & Basic & 107 TB &  5 cut-out image cubes (each with estimated 896 good channels, 2MHz wide at the highest resolution possible) per source. Estimated compression factor of 200 due to cut-out and potential spectral averaging (TBD). \textbf{LR Note: since it is not clear the NRAO can even produce cutout images around all bright sources at 128 MHz resolution, this should be dropped from "Basic".}\\ (TBD).\\  Cumulative basic object catalog & Basic & insignificant &  Brightness, extent and other parameters per source from cumulative continuum images. \\  Enhanced single-epoch continuum images & Enhanced & 158 TB & 

11 images (as for QL) for cumulative hi-res and tapered data. \\  QL transient alerts & Enhanced & insignificant &  VLASS properties (brightness, location, Stokes I and uncertainty cut-outs) from QL processing for each source known to change (TBD). \\  \textbf{Complex Faraday spectra cutouts} & 54 TB & Enhanced & Assumes compression of 200 (bright sources), $|$RM$|<$4000 \frac{rad}{m$^2}\\  \end{tabular}   \end{table}
