Fix sign bug in eta extrapolation #370

Closed dinyar closed 7 years ago

dinyar commented 7 years ago

Currently the dEta value returned by the corresponding LUT is always added to the value received from the track finders. For negative values of pseudorapidity this leads to the correction being applied "in the wrong direction". For those muons with negative eta the sign of the correction therefore needs to be flipped.

We're extrapolating in the "wrong direction" (i.e. adding instead of subtracting dEta and vice versa).

Tests pass.
