The Muon Followers Cut

This cut looks for muon followers by marking events within a time window of a muon. This uses the same algorithm to identify muons as the muon followers tag, without the option to look for missed muons. The cut has two time windows that it uses, one that is short and designed to mark short lived spallation products, the other is desinged for long lived spallation products, and is typically much longer than the short window. The two time windows are independent so any event marked in the short time window is also marked in the long. The muons themselves are marked by the muon bit.

Parameters for the muon followers cut are in the RAAS 8 bank. This contains the eight parameters for the muon cut, and two unique to the followers cut, the two time windows.

The muon followers cut is called in the RAA by:

   call($raa_muon_followers_cut)

The results of the muon followers cut should be sorted using the BITS dqf, for example in a programmable filter:

$enable_test 1
$define_test 1 $line_1 'mu_fol_s bits ANAL+$KANAL_STATUS,$kraa_mu_fol_short,1;'

$enable_test 2
$define_test 2 $line_1 'mu_fol_l bits ANAL+$KANAL_STATUS,$kraa_mu_fol_long,1;'

These filters will return positive for any marked event.
