_ (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.

Handy Tables

The Handy Tables (Greek: Πρόχειροι κανόνες, ‘Handy Tables’) are a set of astronomical tables, together with canons for their use. Only the canons are extant in their original version. The tables themselves are known through Theon of Alexandria’s version. The Handy Tables do not survive as such in Arabic and in Latin (but see A.7.1), even though they represent the prototype of most Arabic and Latin astronomical tables.
