Notes. Columns are: (1) GMF ID; (2) GMF name; (3) Galactic longitude of center of the ellipse that is obtained through fitting the region with AV >  3 mag in the 13CO-based extinction map; (4) Galactic latitude of center of the ellipse; (5) area encompassed by contour level of AV = 3 mag; (6) length of major axis of the ellipse; (7) aspect ratio of the ellipse, defining as the ratio of major axis to minor axis of the ellipse (8) distance adopted from literature; (9) velocity range (vmin and vmax) and central velocity (vLSR) adopted from literature or calculated based on 13CO (J = 1−0) (see Appendix A for details); (10) mean line width of 13CO (J = 1 − 0); (11) total gas mass obtained through integrating in the 13CO-based extinction map down to AV = 3 mag. The uncertainties are from the variations of 13CO abundance and extinction temperatures (see Appendix D for details).; (12) dense gas mass obtained through integrating down to AV = 7 mag. The uncertainties are from the variations of 13CO abundance and extinction temperatures. (13) free-fall time calculated based on spherical morphology assumption. The associated uncertainties are from mass uncertainties; (14) free-fall time calculated based on filamentary morphology assumption. The associated uncertainties are from mass uncertainties; (15) gas surface density (Mcloud/Area) whose uncertainties are from mass uncertainties; (16) mass per unit length, whose uncertainties are from mass uncertainties; (17) Galactocentric radius; (18) height above the Galactic midplane; (19) reference as shown below. We note that the associated uncertainties of the parameters listed in this table do not include the distance errors (also see Appendix D for more information).
