Below, the data of the gaussian fits obtained in the observed HI and CO spectra at each interval of 1° and 2° in longitude for HI and CO (in the galactic plane, i.e. b = 0°, respectively. The data for HI were obtained from the Berkeley survey (Weaver & Williams, 1973) which covered galactic longitudes in the range 10° < l <  250° Parkes (Kerr et al. 1986) with observations from l = 240° to 350° and with the NRAO survey with observations performed for the galactic center covering the longitudes -11° < l < 13° (Burton \& Lizst 1993, BL93). The CO data were obtained from the Columbia survey (Dame et al. 1987, 2001).

The file structure corresponds to:

galactic longitude, area, vlsr, width, peak for both HI and CO data
