To apply an
op.and operation, N parameters are on top of the stack: N-1 Geo Time Series™ lists and one labels List. According to those labels, it produces multiple equivalence classes from the GTS inside those N-1 lists (if they match the same labels as the equivalence class). Then
op.and is applyied to the GTS in those classes, building only one result GTS for each class.
op.and operation will applies AND at each tick on values of all the GTS belonging to the same class (in the order they are passed). The elevation and location are cleared. To produce a result, all GTS of a same class must have a value at a same tick.
If the first value found isn’t a boolean, all values produced will be false.
The name of the resulting GTS is the one of the last GTS of the equivalence class. The labels kept are the one of the equivalence class.
