Comparison between SFTs with Direchlet kernel sizes 16 and 64
Overview
I compared Xavier's SFTs which were generated using Direchlet kernel sizes 16 and 64.
These SFTs were produced from uncalibrated data.
The power plots describe the difference between power computed from SFT coefficients.
The SFT plots describe the distance between two coefficients as complex numbers.
Two flavors of plots are available for comparison:
- "Absolute" plots are distance between these two numbers, as is.
- Relative plots divide the value by the value of power (or square root of it, as appropriate)
computed using data for SFT with Direchlet kernel size 64.
All plots are logarithmic.
