[ferret_users] [ferret]-how to define irregular z-axis

["Yogesh K. Tiwari" <ktiwari@xxxxxxxxxxxxxxx>]

Hello Ferret Users,

I have a netcdf data and when I use this 
ferret says as follows :-

yes? use q.nc
 *** NOTE: Units on axis "sig_s" are not
           recognized: sigma_level
 *** NOTE: They will not be convertible:
 *** NOTE: bounds "bounds_LAT" do not enclose
           point on axis LAT
 *** NOTE: Substituting coordinate midpoints
 *** NOTE: bounds "bounds_LON" do not enclose
           point on axis LON
 *** NOTE: Substituting coordinate midpoints


In fact the veritical axis is irragular 
pressure axis in mb(19 mb pressure values on 
the place of 19 sigma level values) :-

  999.956798673119
  982.300930711410
  958.711821388422
  923.727954421369
  872.668797870758
  802.135476614033
  710.819107916518
  600.936070971621
  480.335709752363
  363.907443320277
  269.693181583253
  205.375139312848
  159.597308168984
  120.320114961464
  86.0958233667092
  57.7252298204432
  35.5095334329671
  19.1474920954818
  7.76486715808502

My question is how to define the irregular 19 
pressure axis values instead of each 19 sigma 
level  while reading and ploting the data.

Thanks,

Yogesh
