mapv takes the refined equilibrium data eqb1 from Jsolver, and output two files mpout1 and mapdsk for nova. It is available through lmhd svn repository svn+ssh://svnsrv.pppl.gov/svn/mhd/trunk/mapv. The syntax is 
 
  mapv
The preallocated fixed array sizes are given as nq for theta grids and ny for radial grids in file clichpar.h : 
      prameter(ns=nmbrgrd,nt0=mnths0,nt=nt0+5, nq=526,ny=526,nsgrd=526)
The meaning of nq and ny are the same as defined in mapck. The actual array sizes are changed at runtime in namelist comap 
 &dfun /
p
 &wdat nosuri=201, mthi=128, igrid=1 /
or 
 &dfun /
p
 &wdat nosuri=129, mthi=128, igrid=1 /
and these changes should be matched in file gridparam: 
      parameter(nmbrgrd=201,mnths0=128,ndat=50)
or 
      parameter(nmbrgrd=129,mnths0=128,ndat=50)
