It should be the number of frequencies.
For each source (8064) you have 1025 values of power density, one per frequency . (frequencies ranging from 0 Hz to 100Hz with 97.65625mHz step).
This tutorial<https://www.nmr.mgh.harvard.edu/mne/stable/auto_examples/time_frequency/plot_source_power_spectrum.html#sphx-glr-auto-examples-time-frequency-plot-source-power-spectrum-py> should help you understand how it works ( especially the last plot)


Best,
Victor

The total time I have considered is 574 seconds so how it is related to 1025 time points.
