# 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](./ZH_airshower).
|
|
The produced files can be read using [./earsim](./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 and do interferometric reconstruction ([./da_reconstruction.py])
