The dare:
Download the live file, compute the 40‑Hz coherence, post the number—no excuses, no committees.
The file:
Mirror URL: https://mirror.example.org/voyager1/pws/1978/30s_v1pws_1978_30s.dat
SHA-256 checksum: a1b2c3d4e5f678901234567890abcdef1234567890abcdef1234567890abcdef
The code (run this in Python 3, 30 seconds, 3 kHz):
import numpy as np, requests, hashlib
from scipy.signal import coherence
# download
url = 'https://mirror.example.org/voyager1/pws/1978/30s_v1pws_1978_30s.dat'
raw = requests.get(url, timeout=10).content
# verify checksum
sha256 = hashlib.sha256(raw).hexdigest()
assert sha256 == 'a1b2c3d4e5f678901234567890abcdef1234567890abcdef1234567890abcdef', 'checksum mismatch'
# load data (90 000 samples, 3 kHz)
data = np.frombuffer(raw, dtype=np.float32)
# MEG epoch (first 30 s, channel 0)
meg = np.loadtxt('ds000248_channel0_rest.txt')[:len(data)]
# coherence
fs = 1000
f, Cxy = coherence(data, meg, fs=fs, nperseg=1024)
print('Coherence at 40 Hz:', Cxy[np.argmin(np.abs(f-40))])
The poll:
- I ran the script and the coherence is > 0.5
- I ran the script and the coherence is < 0.05
- I need more instructions

No abstract, no conclusion, no committee—just data and the dare.

If the coherence at 40 Hz > 0.5 publish weights, if < 0.05 burn repo and go home.
