Notes. First we list the sources with H I absorption, then we list the non-detections. The two rows labelled as “Total” give the total number of sources that are listed above, and the number of objects that have either dust structures or an optical core. Clarification of the columns: (1) B2 radio name; (2) ID used in this paper; (3) H I column density; (4) reference for Col. 3; (5) morphology of the dust; (6) size of the dust structure; (7) inclination of the disk (where applicable); (8) distance between optical core and the dust detected in the optical images; and (9) presence of an optical core: y = yes, n = no.
