Making Spiral Arm Maps with whampy

The SkySurvey class has a method :method:`~whampy.whampyTableMixin.get_spiral_slice` to quickly extract sky section maps with the survey using tracks in longitude-velocity space. whampy comes pre-loaded with spiral arm tracks from `Reid et al. 2016`_.

>>> from whampy.skySurvey import SkySurvey

>>> # Load Survey
>>> survey = SkySurvey()

>>> # Extract Perseus Arm Map
>>> perseus_arm = survey.get_spiral_slice(track = "perseus", lrange = [0,50])
>>> # Sky Map

>>> fig = perseus_arm.intensity_map(colorbar = True, s_factor = 2,

… cbar_kwargs={“orientation”:”horizontal”})
