_ (the underscore) is the placeholder for exactly one character.
% (the percent sign) is the placeholder for no, one or more than one character.
%% (two percent signs) is the placeholder for no, one or more than one character, but not for blank space (so that a search ends at word boundaries).

At the beginning and at the end, these placeholders are superfluous.

Ptho<lome>us in hoc loco tricas et tricarum nomina posuit… (243ra) Stelleque cum caude sunt … [one erased word] — in regibus et divitibus apparebit. Explicit Centilogium Ptolomei. Deo gracias.’
