How-To: Calibrated CTX data

This is a brief how-to showing how the automatically handled raw data can be calibrated using ISIS and how the planetarypy module can help working with the calibrated data.

Requires the CTX package

This page uses functionality that ships separately as of planetarypy 0.82.0. Install it with pip install "planetarypy[ctx]" (or pip install planetarypy-ctx); a core-only install will not have it.
