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.
