SUMMARY
Writes a SAC file containing the spectral estimate.
SYNTAX
[W]RITE[SPE] {file}
INPUT
file: The name of the SAC file to write.
DEFAULT VALUES
WRITESPE SPE_
DESCRIPTION
The spectral estimate file contains the spectral estimate from zero up to the folding frequency. The spectral estimate is calculated with an FFT. The number of points in this file is half the length of the FFT used plus one.
This format was chosen so that multiple spectra computed with SPE could be compared using the P2 plotting function, without any need to cut the files prior to plotting.
