The file hdf200bg is a binary file in standard HDF (version 4) format. Datasets are 2-dimensional polar-grid, with radial velocity, tangential velocity and density. These data were writting with a fortran subroutine hdfall.

% tsd hdf200bg 
Found 3 scientific data sets in hdf200bg
1: R-VELOCITY AT TIME=1.00E+00(154,251) km/sec  -> [38654 elements of type: 5 (FLOAT32)]
2: PHI-VELOCITY AT TIME=1.00E+00(154,251) km/sec  -> [38654 elements of type: 5 (FLOAT32)]
3: DENSITY AT TIME=1.00E+00(154,251) Msolar/pc**2  -> [38654 elements of type: 5 (FLOAT32)]

(6-jun-01) Shortly there will be a lively example and animation of converting this data into something that can be compared to real data.
