Notes. ID: identifier of the cores used in the model. RA: right ascension of the density component given in units of hours:minutes:seconds in the equatorial coordinate system. Dec: declination of the density component given in units of degrees:arcminutes:arcseconds in the equatorial coordinate system. dz: displacement along the line of sight with respect to the model center. The z-axis is oriented such that it points towards the observer. r0: radius defining the density profile as described in Eq. (3). η: exponent of the density profile. n1: central density of H2. n2: central density of CH3 CN. vz : velocity component along the line of sight. Star: this columns indicates whether an additional star was included at the center of the core. If this is the case, the spectral type of the star is given.
