sq97 debug running

sq97 has several debug switches, which are useful in tracking down problems or just understanding the fitting process.

• -dI Input
  This switch activates trace-messages which list the input data to sq97, and includes details of particle identification, if selected (see the -K, -I and -E switches under usage).

  -dF

  This switch activates trace-messages which list all the main vertex fits as squaw does them, before one (or none) is selected by the hypotheses arguments (see the -H and -A switches under usage).

  -dG

  This switch activates trace-messages which list all the decay vertex fits as squaw does them.

  -dO

  This switch activates trace-messages which list the main vertex fits, as they are output.

  -dP

  This switch activates trace-messages which list the decay vertex fits, as they are output.

  -dT

  This switch activates trace-messages which follow the topologies as they are attempt to be fit. This is useful in determining why fits aren't being done, when they are (erroneously) expected.

  -dm

  This activates the msg shared memory option. sq97 can then be monitored with the msg Tcl/Tk gui (see details under msg, or just type "msg &" and press "Help").
