  • Example

    python -m hifast.waterfall data_S/M33_OTF_1_MultiBeamOTF-M*_W-XXX-specs_T-flux.hdf5

  • Input hdf5 files generated during the hifast processing, multiple files can be specified using wildcards.

  • Key parameters:

    • -s：By default, the input files are grouped, and the 19 beams observed on the same day are plotted on one chart for output.

      Adding -s will draw each file separately and save it in the file.

    • --vmin, --vmax: The data range used for the colormap in the chart. You can specify a number or a percentage. The default setting is

      --vmin per0.01 --vmax per95.
