Using the HANDOFF IRFs

There are two versions of response functions based on the handoff analysis: Pass4_v1 and Pass4_v2. The main difference between these is a change in the reconstructed energy distribution. Use:

• Pass4_v1 with the year-long obssim2 simulation.

• Pass4_v2 with the 55day and the 3hour datasets.

Likelihood:

• For ST v8r2, you will need to set the IRFs to HANDOFF explicitly. To do this, you need to include: rspfunc=Pass4_v1 or rspfunc=Pass4_v2 at the command line when you run the likelihood tool.

• For ST v9, you will be prompted for the irfs as with the other parameters and so do not need to provide them at the command line.

• In ST v9r1, the parameter name will change from "rspfunc" to "irfs".

For gtselect: The prompt still refers to DC2 IRFs (we will change this soon). However, the tool will work correctly with handoff IRFS used for obssim2. Use:

• 0 to select front converting events
• 1 for back converting events
• -1 to include both front and back.

To explore the handoff IRFs directly with IrfLoader, you should select:

• "Pass4_v1/front" and "Pass4_v1/back",

or

• "Pass4_v2/front" and "Pass4_v2/back".

In gtrspgen, you should select:

• "Pass4_v1" or "Pass4_v2" if you are considering both front and back events;

otherwise it is:

• "Pass4_v1/front", "Pass4_v1/back",

or

• "Pass4_v2/front", "Pass4_v2/back".
