Askaryan Radio Array (pyrex.custom.ara)

The ARA module contains classes for antennas and detectors as found or proposed for the ARA project.

The HpolAntenna and VpolAntenna classes are models of ARA Hpol and Vpol antennas using data lifted from AraSim. They use the antenna directional gains in data/Hpol_original_150mmHole_Ice_ARASim.txt and data/Vpol_original_CrossFeed_150mmHole_Ice_ARASim.txt respectively, and the electronics gains in data/ARA_Electronics_TotalGain_TwoFilters.txt. The trigger condition of these antennas is based on a comparison of the maximum value of the tunnel-diode-convolved waveforms with the rms value of a tunnel-diode-convolved noise waveform.

The ARAString class creates a string of alternating HpolAntenna and VpolAntenna objects, as in a typical ARA station. The PhasedArrayString class implements a more densely-packed string of antennas which trigger based on a threshold trigger on the best beam-formed combination of the antenna waveforms. The RegularStation class creates a station at the given position with 4 (or another given number) strings spaced evenly around the station center. The PhasedArrayStation class creates station with a phased array string at the station center, and 4 (or another given number) outrigger strings spaced evenly around the station center. The HexagonalGrid class creates a hexagonal grid of stations, spiralling outward from the center.
