IceCube Radio Extension (pyrex.custom.irex)

The IREX module contains classes for antennas and detectors which use waveform envelopes rather than raw waveforms. The detectors provided allow for testing of grid and station geometries.

The EvelopeHpol and EvelopeVpol classes wrap models of ARA Hpol and Vpol antennas with an additional front-end which uses a diode-bridge circuit to create waveform envelopes. The trigger condition for these antennas is a simple threshold trigger on the envelopes.

The IREXString class creates a string of EvelopeVpol antennas at a given position. The RegularStation class creates a station at a given position with 4 (or another given number) strings spaced evenly around the station center. The CoxeterStation class creates a station at a given position similar to the RegularStation, but with one string at the station center and the rest spaced evenly around the center. The StationGrid class creates a rectangular grid of stations (or strings, as specified by the station type). The dimensions of the grid in stations is Nx by Ny where N is the total number of stations, Nx=floor(sqrt(N)), and Ny=floor(N/Nx).
