#### Type 2000

Type 2000 files contain a two-dimensional array of data values, such as an ambiguity function or power spectra versus time. The file is organized into frames, each of which looks like a Type 1000 file. A Type 2000 file is simply a stack of frames where each frame corresponds to the x-dimension and is stacked in the y-dimension. The header describes both the physical abscissa information for the frame, and the physical ordinate (y-axis) information for the stack:

- physical abscissa (frame) units
- physical abscissa (frame) starting value
- physical abscissa (frame) increment
- frame length
- physical ordinate units
- physical ordinate starting value
- physical ordinate increment
