    v70 v71  
    8080 2. Center frequencies 1440.5mHz(fc1), 1442.5mHz(fc2), 1444.5mHz(fc3) for out-of-band
    8181- Identified clean vs. RFI-contaminated signal shapes in Power Spectral Density (PSD) plots:
    82  1. Uniform (Clean): flat-top spectrum, power emitted uniformly across bandwidth
    83  2. Spikes (RFI): abrupt, sharp spikes in power at random frequency levels
    84 [[Image(https://www.orbit-lab.org/raw-attachment/wiki/Other/Summer/2025/mlCoexist/PSD%20clean.png, 30%)]]
     82 1. Uniform (Clean, L): flat-top spectrum, power emitted uniformly across bandwidth
     83 2. Spikes (RFI, R): abrupt, sharp spikes in power at random frequency levels

    8586
    8687- Determined brightness temperature thresholds for various gain levels and labeled the dataset as clean = 0 or RFI-contaminated = 1 (link to [https://colab.research.google.com/drive/1HNY1UFtT_i09UoGw7iyH8hQBkvqFWRB1?usp=sharing code])
