[MITgcm-support] exp0 with non-constant bathymetry

[Sergey Vinogradov]

Matt, Samar:
Indeed, there is a problem with my Depth.data. I'm changing the hFacMin 
to 0.1 (< shallowest bathymetry/layer thickness). However, if I put 
hFacMin into data file (in PARM04 group ), it cannot digest it "namelist 
read: read unexpected character". Can you change this parameter only in 
a source code?
Thanks
Sergey
