Notes. (1) The first to third columns list the source names and equatorial coordinates. PGCCs all have names starting with the letter “G”, followed by their Galactic coordinates. The fourth to eighth columns list the distance, source size (Ddust), Planck dust temperture of a whole clump(TECC), dust temperature (Tdust) extracted from the Planck all-sky map, and column density of H2 (Ndust (H2)) derived from the dust emission. The values in parentheses are 1-σ uncertainties. (2) This column shows the scanning modes for H I observations by the FAST, with T and S representing tracking mode and snapshot mode, respectively. (3) The zenith angle of the source when observed with the FAST. (4)The distance of L1489 region is quoted from Myers et al. (1988); Wu et al. (2019a), while the angular size is obtained based on Herschel 500 μm map (Yen et al. 2014; Wu et al. 2019a). (5)The distance of L1521B is quoted from Hirota et al. (2004). (6)IRAS 05413-0104 is the driven source of the known collimated bipolar jet HH 212, with a distance of 400 pc (Reipurth et al. 2019). (7) The distance of HH25 MMS is quoted from Gibb & Davis (1998); Wu et al. (2004). (8) The distance of CB34 is quoted from Yun & Clemens (1994); Khanzadyan et al. (2002).
