Function Documentation

def tcc.parse.getCoordSys.getCoordSys

(

param

)

Obtain a coordinate system from a parsed parameter.

Parameters

[in]

param

the parsed parameter

Returns

a coordinate system as a shared_ptr to a subclass of coordConv.CoordSys, or None if not present (returning a shared_ptr allows the result to be used to set Obj.userSys)

Exceptions

twistedActor.CommandError

if the coordinate system is unrecognized

Definition at line 31 of file getCoordSys.py.

def tcc.parse.getCoordSys.makeCoordSys	(		name,
			date
	)

Make a coordinate system from its name and date.

Unlike coordConv.makeCoordSys this supports focal plane coordinate systems

Parameters

[in]	name	coordinate system name used by the command parser (case insensitive)
[in]	date	coordinate system date, or None for default date
