This is what the Unicode charts have to say about this:

| * not to be confused with the actual stigma letter
| -> 03DB ? greek small letter stigma
|
| 03C3 σ GREEK SMALL LETTER SIGMA
| * used symbolically with a numeric value 200
|
| [...]
|
| 03DA ? GREEK LETTER STIGMA
| * apparently in origin a cursive form of digamma
| * the name "stigma" originally applied to a medieval sigma-tau ligature,
whose
| shape was confusably similar to the cursive digamma
| * used as a symbol with a numeric value of 6
|
| 03DB ? GREEK SMALL LETTER STIGMA
| -> 03C2 ς greek small letter final sigma
|
| 03DC ? GREEK LETTER DIGAMMA
|
| 03DD ? GREEK SMALL LETTER DIGAMMA
| * used as a symbol with a numeric value of 6

So, apparently, there are three totally unrelated letters which have been
called "stigma" in the course of time:

1) an old sigma+tau ligature (encoding: 03C3 followed 03C4);

2) a cursive form of digamma (encoding: 03DA or 03DC), called
"stigma" because it looks like (1) above;

3) the final form of lowercase sigma (encoding: 03C2), called
"stigma" because it looks like (2) above (which, in turns, looks like (1)!).

Considering the bracketed explanation in your document, I would say that the
correct transcription is (1), although that makes the bracketed explanation
quite ridiculous:

Dηnaστartarωθ [στ = st]

You should probably underline or italicize the "στ", and add a note to make
it clearer that it is a legated symbol and not the two ordinary sigma and
tau letters.

Although the Unicode chart does not show it, also the modern final sigma
("ς") is also as a symbol for numeral 6 (in place of the digamma,
which is obviously missing from most fonts intended for modern Greek).
