How do I create a plot of an image?
Images can be created using either make_figure or add_image:
make_figure("img.fits", "image") make_figure("img.fits", "image", ["colormap", "heat"]) add_image("img.fits") add_image("img.fits", ["colormap", "heat"])
The ChIPS Gallery
More examples can be seen in the ChIPS Gallery.
The add_contour, add_image, and make_figure commands will warn you if given an image with an unsupported WCS projection (that is, everything but a tangent-plane projection), and fall back to using the physical or logical systems. An example of the warning is:
chips WARNING: Unable to use world transform - RA---SIN, DEC--SIN is an unsupported type. Using physical transform.
