Latitude

class astropy.coordinates.Latitude[source] [edit on github]

Bases: astropy.coordinates.Angle

Latitude-like angle(s) which must be in the range -90 to +90 deg.

A Latitude object is distinguished from a pure Angle by virtue of being constrained so that:

-90.0 * u.deg <= angle(s) <= +90.0 * u.deg

Any attempt to set a value outside that range will result in a ValueError.

The input angle(s) can be specified either as an array, list, scalar, tuple (see below), string, Quantity or another Angle.

The input parser is flexible and supports all of the input formats supported by Angle.

Parameters:

angle : array, list, scalar, Quantity, Angle. The

angle value(s). If a tuple, will be interpreted as (h, m, s) or (d, m, s) depending on unit. If a string, it will be interpreted following the rules described for Angle.

If angle is a sequence or array of strings, the resulting values will be in the given unit, or if None is provided, the unit will be taken from the first given value.

unit : UnitBase, str, optional

The unit of the value specified for the angle. This may be any string that Unit understands, but it is better to give an actual unit object. Must be an angular unit.

Raises:

`~astropy.units.UnitsError`

If a unit is not provided or it is not an angular unit.

`TypeError`

If the angle parameter is an instance of Longitude.
