plate_carree-1.0.0

The plate carrée projection.

Description

Corresponds to the CAR projection in the FITS WCS standard.

The main virtue of this transformation is its simplicity.

The pixel-to-sky transformation is defined as:

\[\begin{split}\phi &= x \\ \theta &= y\end{split}\]

And the sky-to-pixel transformation is defined as:

\[\begin{split}x &= \phi \\ y &= \theta\end{split}\]

Invertibility: All ASDF tools are required to provide the inverse of this transform.
