caesura or other ornamentation ?.

[eby_km]

Hello all, i'm typesetting a handwritten score found on internet, it does have 
several marking similar to "caesura" and "fermata + caesura" above the note 
itself and many youtube recordings this is played with "prall" variants for 
those weird markings, can someone confirm whether these are indeed "caesura" or 
some other ornamentation in the attached example ?.

Thanks,
