+# CCD Processing
+
+This section explains the various processing taking place in the "radios" domain.
+
+## Introduction
+
+Once a radios chunk is loaded into memory (see [radios chunk processing](definitions.md#radios-chunks)), various processing can be applied to each individual (sub)radio. The most common are:
+  - CCD hotspots removal
+  - Flat-Field normalization
+  - Phase retrieval
+
+## The `CCDProcessing` class
+
+The base class for handling these processing is `CCDProcessing` found in `nabu.preproc.ccd`.  To instantiate a `CCDProcessing` class, only a stack of radios is required.
