SLIC takes .stdhep files as input. If you have .lhe files that you want to process (usually tridents or A' signal), it may be better to use an existing script for this step, or else contact Brad Bradley Yale for instructions (btu29@wildcats.unh.edu).

...

The following steps simulate readout, which defines things like trigger response and prescaling taken from a steering file.

Note: If using a detector with a fieldmap, then a symbolic link to the fieldmap directory must be made, if not done already (see previous section).

1) Before the actual readout, the events from SLIC output will first need to be spaced out to simulate pileup:

...

where ${hps-java} = /u/group/hps/hps_soft/hps-java/hps-distribution-3.4.1bin.jar

'hps-distribution-bin.jar' links to whichever jar in the 'hps-java' directory is most recent (this can of course be changed),

or whichever jar you want to use, and
${steering} = EngineeringRun2015TrigSingles1_Pass2.lcsim
or whichever customized readout steering file you want to use.

If you want to use your own steering file other than the release version for anything in the readout or recon steps, replace
"-r /org/hps/steering/recon/${steering}"
with
"-f /path/to/your/${steering}" without the '-r' flag.

The run number can also be replaced.

...

1) Finally, recon is run using:

java OLD WAY: java -DdisableSvtAlignmentConstants  -XX:+UseSerialGC -Xmx500m -jar ${hps-java} -r /org/hps/steering/recon/${steering} -i {in}.slcio -DoutputFile={out} -Ddetector=${detector} -Drun=5772
New Way:   java -DdisableSvtAlignmentConstants  -XX:+UseSerialGC -Xmx500m -jar ${hps-java} -r /org/hps/steering/recon/${steering} -i {in}.slcio -DoutputFile={out} -d${detector} -R5772

To make a DST using the recon output:

source /u/group/hps/hps_soft/setup_dst.csh

/u/group/hps/hps_soft/hps-dst-0.9/build/bin/dst_maker {in}.slcio -o {out}.root -g -b .24

'hps-dst' is linked to the latest version of the dst_maker.

Note: If using an HPS jar before GBL was integrated into the trunk, then a '-g' switch must be added to the command in order to include GBL tracks in the resulting DST file, and also a flag to set the correct magnetic field for 1.056 GeV running.

i.e. "dst_maker {in}.slcio -o {out}.root -g -b .24"

 This sets the magnetic field to 0.24 T, for 1.05 GeV running, and adds GBL tracks to the output.
