LAT GRB Analysis Tutorial - Get LAT Data

At your workstation

1. For SCons builds (e.g., ScienceTools-09-15-04), see the Fermi LAT New Release Manager.

Note: At the time this was written, the SCons ScienceTool builds available were redhat3-i686-32bit-gcc32 Optimized, and they had to be run in a bash shell.

To view the build status and location:

1. Select:

Package = Science Tools
Version = Release Builds
Time Span = None

2. Click on the Filter button.
3. Under operating system, identify the Build you are interested in (e.g., ScienceTools-09-15-04), then select redhat3-i686-32bit-gcc32 Optimized.
4. Click on the GO button.

2. From the workbook's LAT Data Access (green navbar) page.
   1. Click on the Data Portal button.
   2. Then select the Astro Server tab.

3. For the purposes of this exercise, we'll be analyzing GRB 080916C.
   Enter/select the following to obtain the data:

1. Job Name — enter a meaningful name for your job
2. Event Sample — select p6_public_v1
3. Energy Range — Min: 100 Max:300000
4. Time Range — Min: 243216415 Max: 243217115
5. Position — RA: 119.88 DEC: -56.59
6. Radius — 15.0 degrees
7. Event Classes — Diffuse
8. Output — FT2 30 second (fits) and 1 second (fits).
9. Output — FT1 (fits); Event-List (text)
10. Debug Mode — False
11. User Comment — optional
12. Click on the Proceed button

The job summary will be displayed:

4. Verify and correct the information, then click on the submit button.

When your job has completed you will receive an email from DataPortal@slac.stanford.edu, whic will include your job number (e.g., 1252699617752).

Tip: ftp-glast.slac.stanford.edu/glast.u53/DataServer/your_jobNumber equates to: /nfs/farm/g/glast/u53/DataServer/your_jobNumber.

From your SLAC Public work directory

5. Copy the LAT data files to your SLAC Public work directory; for example:

cp /nfs/farm/g/glast/u27/DataServer/your_jobNumber/*.* .
