I have a question about the Identification Box In 'Cartes Du Ciel'.

When clicking on an object, the Info box opens and lists stuff about the object. I use it regularly. But what I can't find anywhere is an explanation as to the Abbreviations used to decribe Galaxies.

I have circled in Red the bit I am talking about. Does anyone know how to decipher these abbreviations? or where there is a list of their meanings? Please.
