iaxlab - plot axes labels (default: 1)
albht - height of axes labels (mm) (default: 0.2) xmin, xmax - minimum and maximum distance (km) of velocity model xmm - length of distance axis (mm) xtmin, xtmax - minimum and maximum values (km) of tick marks ntickx - number of intervals separated by tick marks along distance axis ndecix - number of digits after decimal in distance axis annotation; -1 for integer annotation (defaults: 0, none, 250; values for xtmin, xtmax, ntickx and ndecix depend on values of xmin and xmax) zmin, zmax - minimum and maximum depth (km) of velocity model zmm - length of depth axis (mm) ztmin, ztmax - minimum and maximum values (km) of tick marks ntickz - number of intervals separated by tick marks along depth axis ndeciz - number of digits after decimal in depth axis annotation; -1 for integer annotation (defaults: 0, 50, 75; values for ztmin, ztmax, ntickz and ndeciz depend on values of zmin and zmax) tmin, tmax - minimum and maximum two-way travel time (s) of 1-D velocity profiles or 2-D model boundary plots tmm - length of time axis (mm) ttmin, ttmax - minimum and maximum values (s) of tick marks ntickt - number of intervals separated by tick marks along time axis ndecit - number of digits after decimal in time axis annotation; -1 for integer annotation (defaults: 0, 10, 75; values for ttmin, ttmax, ntickt and ndecit depend on values of tmin and tmax) vmin, vmax - minimum and maximum velocity (km/s) of 1-D velocity profiles vmm - length of velocity axis (mm) vtmin, vtmax - minimum and maximum values (km/s) of tick marks ntickv - number of intervals separated by tick marks along velocity axis ndeciv - number of digits after decimal in velocity axis annotation; -1 for integer annotation (defaults: 0, 8, 75, values for vtmin, vtmax, ntickv and ndeciv depend on values of vmin and vmax) vrmin, vrmax - minimum and maximum velocity (km/s) of RMS velocity profile vrmm - length of RMS velocity axis (mm) vrtmin, vrtmax - minimum and maximum values (km/s) of tick marks ntckvr - number of intervals separated by tick marks along RMS velocity axis ndecir - number of digits after decimal in RMS velocity axis annotation; -1 for integer annotation (defaults: 2, 7, 75, values for vrtmin, vrtmax, ntckvr and ndecir depend on values of vrmin and vrmax)
