astroquery.alma.utils.make_finder_chart(target, radius, save_prefix, service=<bound method SkyViewClass.get_images of <astroquery.skyview.core.SkyViewClass object>>, service_kwargs={'pixels': 500, 'survey': ['2MASS-K']}, alma_kwargs={'public': False, 'science': False}, **kwargs)[source]

Create a “finder chart” showing where ALMA has pointed in various bands, including different color coding for public/private data and each band.

Contours are set at various integration times.

target : astropy.coordinates or str

A legitimate target name

radius : Quantity

A degree-equivalent radius.

save_prefix : str

The prefix for the output files. Both .reg and .png files will be written. The .reg files will have the band numbers and public/private appended, while the .png file will be named prefix_almafinderchart.png

service : function

The get_images function of an astroquery service, e.g. SkyView.

service_kwargs : dict

The keyword arguments to pass to the specified service. For example, for SkyView, you can give it the survey ID (e.g., 2MASS-K) and the number of pixels in the resulting image. See the documentation for the individual services for more details.

alma_kwargs : dict

Keywords to pass to the ALMA archive when querying.

private_band_colors / public_band_colors : tuple

A tuple or list of colors to be associated with private/public observations in the various bands

integration_time_contour_levels : list or np.array

The levels at which to draw contours in units of seconds. Default is log-spaced (2^n) seconds: [ 1., 2., 4., 8., 16., 32.])
