pulsarbat.FractionalPhase

class pulsarbat.FractionalPhase(angle, unit=None, wrap_angle=None, **kwargs)

Phase without the cycle count, i.e., with a range of 1 cycle.

This subclass of ~astropy.coordinates.Longitude differs from it mostly in being able to take the fractional part of any ~baseband_tasks.phases.Phase input.

Parameters

anglearray, list, scalar, ~astropy.units.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.

unitUnitBase, str, optional

The unit of the value specified for the angle. This may be any string that ~astropy.units.Unit understands. Must be an angular unit. Default is ‘cycle’.

wrap_angleAngle or equivalent, optional

Angle at which to wrap back to wrap_angle - 1 cycle. If None (default), it will be taken to be 0.5 cycle unless angle has a wrap_angle attribute.

Raises

~astropy.units.UnitsError

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

TypeError

If the angle parameter is a Latitude.
