NGC 1530  70 is included in the sample because its red wing component has 
NGC 1530  70  {Delta}v_r_>46.55 km/s     
NGC 1530  73 is considered to satisfy the criterion selection that its wing must
NGC 1530  73  have a velocity separation bigger than 2.5 times the spectral 
NGC 1530  73  resolution of the data cube (46.55km/s), if the estimated error 
NGC 1530  73  for {Delta}v_r_ is considered.
NGC 6951  24 has a single fitted spectrum (apart from the spectrum 1x1) of the 
NGC 6951  24  set of the line profiles extracted with different apertures for 
NGC 6951  24  each region. The parameters for the wings are those for the single
NGC 6951  24  fitted spectrum. Since we have only a single value for each 
NGC 6951  24  parameter we could not obtain the corresponding standard 
NGC 6951  24  deviation. 
NGC 6951  27 has a single fitted spectrum (apart from the spectrum 1x1) of the 
NGC 6951  27  set of the line profiles extracted with different apertures for 
NGC 6951  27  each region. The parameters for the wings are those for the single
NGC 6951  27  fitted spectrum. Since we have only a single value for each 
NGC 6951  27  parameter we could not obtain the corresponding standard 
NGC 6951  27  deviation. 
NGC 6951  36 The red wing feature of region 36 has a velocity separation less 
NGC 6951  36  than 2.5 times the spectral resolution of the data cube 
NGC 6951  36  (39.08km/s), we include it in the sample since the blue wing does
NGC 6951  36  satisfy the criterion.
NGC 3359 140 have a single fitted spectrum of the set of line profiles extracted
NGC 3359 140  with different a pertures for each region. The parameters for the 
NGC 3359 140  wings are those for the single fitted spectrum. 
NGC 3359 192 have a single fitted spectrum of the set of line profiles extracted
NGC 3359 192  with different a pertures for each region. The parameters for the 
NGC 3359 192  wings are those for the single fitted spectrum. 
NGC 3359  56 was kept in the sample although the velocity separation for its red
NGC 3359  56  component is not bigger than 2.5 times the spectral resolution of 
NGC 3359  56  the data cube (41.65km/s). 
NGC 3359  19 The red components of regions 19 and 42 and the blue components of 
NGC 3359  19  regions 42 and 83 satisfy the criterion if the estimated errors 
NGC 3359  19  for {Delta}v_r_ are taken into account.
NGC 3359  42 The red components of regions 19 and 42 and the blue components of 
NGC 3359  42  regions 42 and 83 satisfy the criterion if the estimated errors 
NGC 3359  42  for {Delta}v_r_ are taken into account.
NGC 3359  83 The red components of regions 19 and 42 and the blue components of 
NGC 3359  83  regions 42 and 83 satisfy the criterion if the estimated errors 
NGC 3359  83  for {Delta}v_r_ are taken into account.
