[thredds] NetCDF subset service

Hi All,

Does the NetCDF subset service still accept outputs other than netcdf?

For example I get an error message when using accept=csv
http://motherlode.ucar.edu:8080/thredds/ncss/grid/fmrc/NCEP/GFS/Alaska_191km/runs/NCEP-GFS-Alaska_191km_RUN_2011-08-30T12:00:00Z?var=Pressure&south=40&west=-105&north=43&east=-103&accept=csv

thanks,
Dave
