+Luma-Only Formats
+*****************
+
+This family of formats only store the luma component of a Y'CbCr image. They
+are often referred to as greyscale formats.
+
+.. note::
+
+ - In all the tables that follow, bit 7 is the most significant bit in a byte.
+ - Formats are described with the minimum number of pixels needed to create a
+ byte-aligned repeating pattern. `...` indicates repetition of the pattern.
+ - Y'\ :sub:`x`\ [9:2] denotes bits 9 to 2 of the Y' value for pixel at colum
+ `x`.
+ - `0` denotes padding bits set to 0.
