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.

Parameters:

imagefits.PrimaryHDU or fits.ImageHDU object

The image to overlay onto

catalogastropy.Table object

The catalog of ALMA observations

save_prefixstr

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

alma_kwargsdict

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.])
