Notes. Table columns are as follows: Col. 1: the HVC name of the source as for Table 1; Col. 2: AGC number as in Table 1; Col. 3: the ratio of the WSRT half-flux size to the ALFALFA half-flux size; Col. 4: the ratio of the WSRT integrated flux density to the ALFALFA integrated flux density for both the 210′′ and 105′′ data; Col. 5: the ratio of the peak WSRT column (for both the 210′′ and 105′′ data) to the ALFALFA .

(a)

This source is a non-detection; the peak column density value is based on the moment zero map of the dirty data.
