Source

class Source(source_id: int | integer, name: str, direction: dict, proper_motion: dict[str, dict], is_eph_obj: bool, table_name: str, avg_spacing: float | str)[source]

Bases: object

A logical representation of an astronomical source.

id: The numerical identifier of the source.

name: The name of the source.

fields: List of Field objects for field(s) associated with the source.

is_eph_obj: Boolean declaring whether this is a moving source (with entry in the ephemeris table).

Attributes Summary

`avg_spacing`	Returns the average time spacing (in minutes) between table entries in the ephemeris table or "" if this is not an ephemeris source.
`dec`	Return declination of the source.
`direction`	Return source direction as a CASA 'direction' measure dictionary.
`ephemeris_table`	Returns the name of the ephemeris table associated with this Source or "" if this is not an ephemeris source.
`frame`	Return reference frame code for the direction to the source.
`gb`	Return declination of the source.
`gl`	Return longitude for the source, in DMS format.
`intents`	Return unique scan intents associated with the source.
`latitude`	Return latitude of the source.
`longitude`	Return longitude of the source.
`pm_x`	Return string representation of longitudinal component of proper motion of the source.
`pm_y`	Return string representation of latitudinal component of proper motion of the source.
`proper_motion`	Return string representation of proper motion of the source.
`ra`	Return right ascension of the source.
