NAME

Dip_azim - Display dip and azimuth information


Usage

 Dip_azim dip1=p.H dip2=q.H  >dip_azim_plot.H fn_color=color


PARAMETERS

dip1 - sepfile
   dip in direction 1
dip2 - sepfile
   dip in direction 2
stdout - sepfile
   color coding file
fn_color - sepfile
    color table for Grey
ndim - integer
   [16] Number of dips (saturation)
nazim - integer
   [8] Number of azimuths (hue)
lightness - real
   [.5] Lighness
mirror - integer
   [0]  Mirror effect on color scheme
turn - real
   [0.0]  Turn hue clockwise sirection in degrees
max_dip - real
   [30.0]  Value of maximum dip will be displayed


DESCRIPTION

 Composing apparent dips (p and q components) to form a the true 
    dip and azimuth composite data for color display


EXAMPLES

 Dip_azim dip1=dipx.H dip2=dipy.H >out.H fn_color=color
 Grey  color=color  color16=y  bclip=0 eclip=1024. < out.H |Tube


COMMENTS

 COLOR DESIGN: A constant lightness hue-saturation color palette
               Total number of colors = nhue*nsaturation
 COLOR MAPPING SCHEME: Azimuth (=arctan(q,p)) modulates the hue
                       Dip (=sqrt(p^2+q^2)) modulates the saturation
 KEY OPERATION: dip(:,:)=MIN(max_dip,dip(:,:))
