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.

imagefits.PrimaryHDU or fits.ImageHDU object

The image to overlay onto

catalogastropy.Table object

The catalog of ALMA observations


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


Keywords to pass to the ALMA archive when querying.

private_band_colors / public_band_colorstuple

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

integration_time_contour_levelslist 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.])
