## mrvmp: Month Power (Amplitude) Spectrum

The power spectra is produced with a non-power-of-2 FFT from the time series.

Dimensionally, frequency is along the x-axis, the y-axis contains the order of spherical harmonic, m, from -l to l, and the z-axis contains the power [*,*,1]. The FITS header keyword, CD1_1, gives the conversion factor (microHz/pixels) for the x-axis.
