     5'''command''': VESPA <slow1> <slow2> <slowstep> <azim> <power> 
     6 
     7Computes vespagram from all traces of the display. For each slowness value from <slow1> to <slow2> in steps of <slowsteps> a beam trace is computed (using azimuth <azim>). On the summation the <power>-th root process is applied. <power>=1 means plain summation. The input traces are hidden after execution 
     8of this procedure. To get them back, enter the command "[ShDisplay DISPLAY]` h:all`". Each output trace corresponds to a slowness value. The slowness is given in the "comment"-entry of the trace. It is convenient to switch the trace info text to "comment" by the command "[ShTrcTxt TRCTXT]` ^comment($x)`".

     12 * <slow1>, <slow2> ''parameter type: real''[[BR]] 
     13   Slowness window. Units in deg/sec. 
     14 
     15 * <slowstep> ''parameter type: real''[[BR]] 
     16   Step size within slowness window. Unit in deg/sec. 
     17 
     18 * <azimuth> ''parameter type: real''[[BR]] 
     19   Beam azimuth in degrees. 
     20 
     21 * <power> ''parameter type: real''[[BR]] 
     22   Before each summation the <power>-th root of the input traces is computed. The result trace is then taken to the <power>-th power.
