The diagrams are correct.

Read the third item in the list of Variations in the Wikipedia article titled Helmholtz pitch notation. I chose to use this variation of Helmholtz pitch notation in my example Perl script because it seems more well-suited to computer use and digital typography. One thing that troubled me is that there are no Unicode characters that are low versions of the high prime characters: PRIME U+2032 (′), DOUBLE PRIME U+2033 (″), TRIPLE PRIME U+2034 (‴), etc.
