coordsys.names - Function

1.1.3 Recover the names for each axis

Description

Each axis associated with the Coordinate System has a name (they don’t mean anything fundamental). This function returns those names in world axis order.

You can recover the names 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 names with function setnames.

Arguments


Inputs
type	Coordinate type: ”direction”, ”stokes”, ”spectral”, ”linear”, ”tabular”. Leave empty for all.
	allowed:	string
	Default:

Returns
stringArray

Example

"""
#
print "\t----\t names Ex 1 \t----"
csys = cs.newcoordsys(direction=True, spectral=True)
n = csys.names()
print n[0]
#Right Ascension
print n[1]
#Declination
print n[2]
#Frequency
print cs.names(’spec’)
#Frequency
#
