LOFAR antenna database
Module for manipulating LOFAR antenna databases. Typical usage is to create an instance of a LofarAntennaDatabase:
>>> import lofarantpos.db
>>> db = lofarantpos.db.LofarAntennaDatabase()
>>> cs001lba_etrs = db.phase_centres['CS001LBA']
array([3826923.942, 460915.117, 5064643.229])
>>> db.antenna_pqr('RS210LBA')[:5]
array([[ 0. , 0. , 0. ],
[-0.00006..., 2.55059..., 0.00185...],
[ 2.24997..., 1.3499502 , 0.00130...],
[ 2.24982..., -1.35031..., -0.0004149 ],
[ 0.00006..., -2.55059..., -0.00185...]])Some functions are included to convert xyz coordinates to latitude, longitude, height w.r.t. WGS84 ellipsoid.
>>> from lofarantpos.geo import geographic_from_xyz
>>> geographic_from_xyz(cs001lba_etrs)
{'lon_rad': 0.11986275972340964,
'lat_rad': 0.9234780446647385,
'height_m': 50.162683041766286}Installation
This module can be pip-installed:
pip install lofarantpos
Alternatively, install it from this source with
python setup.py install
Note This package used to be called lofar-antenna-positions. It may be
necessary to uninstall lofar-antenna-positions before installing.
