# Piner, Stone & Teuben: 1995

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.
