psdDF2NoiseMatrix function uses the

not supplied as an argument. This correction is applied to every PSD in
the dataframe and the now corrected PSD values are returned as a matrix.

matrix is returned with one row for each instrument-corrected PSD and one column for each frequency bin.
The incoming dataframe is checked to make sure that it represents only a single SNCL (Station-Network-Channel-Location). An error is generated if
more than one is found. However, the
psdDF is not checked to make sure that no changes to the
instrument correction happened during the time period covered by the
psdDF. This occurs at an 'epoch'
boundary when an instrument is replaced.
