Routines

Coordinates

coordinates.py contains dependency-free fast routines to parse/format sexagesimal coordinates.

Lookup Objects

Lookup for objects/targets parameters using one of its aliases. Uses Objects.database nad TAB.ALL files.

Example

>>> from pyaraucaria.lookup_objects import ObjectsDatabase
>>> od = ObjectsDatabase()
>>> od.lookup_object('lmc105_8_11987')
{'name': 'CEP25', 
 'ra': '05:18:12.8', 
 'dec': '-71:17:15.4', 
 'per': 3.4050955, 
 'hjd0': 2160.55457, 
 'aliases': ['LMC-T2CEP-085', 'lmc105.8_11987', 'lmc105_8_11987', 'cepii_lmc105_8_11987'], 
 'hname': 'LMC-T2CEP-085'
}

Command Line

$ lookup_objects -j hd167003
{"hd167003": {"name": "HIP37", "ra": "18:14:43.3", "dec": "-33:08:41.8", "aliases": ["hd_167003", "hd167003"]}}
