vice.milkyway.annuli

Type : list [elements of type float]

The radii representing divisions between annuli in the disk model in kpc. This property is determined by the zone_width attribute, and cannot be modified after initialization of a milkyway object.

See also

vice.milkyway.zone_width

While this attribute stores the radii representing bounds between annuli, the singlezone object corresponding to each individual annulus is stored as an array in the zones attribute, inherited from the multizone class.

By default, they will be named where “zone0” is the zero’th element of the zones attribute, corresponding to the innermost zone. The second innermost zone will be the first element of the zones attribute, and by default will be named “zone1”, and so on.

Example Code

>>> import vice
>>> mw = vice.milkyway(name = "example", zone_width = 0.2)
>>> mw.annuli
[0.0,
 0.2,
 0.4,
 ...,
 19.6,
 19.8,
