Airshower + Beacon simulation

Simulate receiving an airshower and beacon in an array. Using the beacon, the clocks can be calibrated.

The ZHaires simulated airshower is stored in ./ZH_airshower. The produced files can be read using ./earsim.

All quantities are stored in HDF5 files with the airshower data.

Steps:

  1. Setup

    1. Beacon ([./aa_generate_beacon.py])

      1. Define tx position
      2. Read in antennas
      3. Sample beacon at each antenna
      4. Add to relevant polarisation
      5. Save antenna traces

    2. Timeoffset ([./ab_modify_clocks.py])

      1. Generate timeoffsets for each antenna
      2. Modify time samples

  2. Beacon analysis

    1. Find beacon frequency and phase in antenna traces ([./ba_measure_beacon_phase.py])
    2. Remove phase due to distances
    3. Analyse the sigma between antenna pairs
    4. Remove 0j part and take the mean of (:,j)
    5. Assign mean as clock shift phase of antenna

  3. Find k*2\pi phase offsets (periods) ([./ca_periods_from_showers.py])

  4. Rewrite clocks
