1.1.3.0 coordsys.telescope

coordsys.telescope - Function

1.1.3 Return the telescope
Description

This function returns the telescope contained in the Coordinate System as a simple string.

The telescope position may be needed for reference code conversions; this is why it is maintained in the Coordinate System.

The conversion from string to position is done with Measures observatory. The example shows how.

Arguments

Returns
string

Example

"""
#
print "\t----\t telescope Ex 1 \t----"
csys = cs.newcoordsys()
print csys.telescope()
#ATCA
print me.observatory(csys.telescope())
#{’type’: ’position’, ’refer’: ’ITRF’,
# ’m1’: {’value’: -0.5261379196128062, ’unit’: ’rad’},
# ’m0’: {’value’: 2.6101423190348916, ’unit’: ’rad’},
# ’m2’: {’value’: 6372960.2577234386, ’unit’: ’m’}}
#
"""

We get the telescope as a string. The Measures system is used to convert from the simple name to a position Measure.
