• In the Form panel, you can either "Import" to create the integrated HEALPix table in TOPCAT at the current scale (2 columns: cell #, plotting parameter; only filled cells are present), or "Save" in a file in HEALPix-fits format (FITS formatting is more efficient than VOTable, as it is compressed).
