coordsys.units - Function

1.1.3 Recover the units for each axis

Description

Each axis associated with the Coordinate System has a unit. This function returns those units (in world axis order).

You can recover the units either for all coordinates (leave type unset) or for a specific coordinate type (mimumum match of the allowed types will do). If you ask for a non-existent coordinate an exception is generated.

You can set the units with function setunits.

Arguments


Inputs
type	Coordinate type: ’direction’, ’stokes’, ’spectral’, ’linear’ or leave unset for all
	allowed:	string
	Default:

Returns
stringArray

Example

"""
#
print "\t----\t units Ex 1 \t----"
csys = cs.newcoordsys(direction=True, spectral=True)
print csys.units()
#["’", "’", ’Hz’]
print csys.units(’spec’)
#Hz
#
