Renamed bibio to misc. In procedure fxhyp, use the fact that xf is an odd function of xtild. In procedure invert_zoom_x, replace linear search in xf by bisection. Also, use result from previous loop iteration as initial guess. Variable "it" cannot be equal to 2 * nmax after search. Unused arguments: hm of cv3_feed; ph, qnk, tv,tvp of cv3_mixing; ppsol of lw; rconst, temp of vdif_kcay; rconst, plev, temp, ustar, l_mix of yamada.
