1. Kim Tolbert The Catholic University of America and Goddard Space Flight Center August 22-23, 2012 1 Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov

2. Object-oriented interface for X-ray spectral analysis of solar data Distributed in SSWIDL August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 2 OSPEX

3. OSPEX runs in SSWIDL  IDL  Proprietary  OSPEX needs IDL > 6.1  SSW (SolarSoftware)  IDL routines for solar data analysis  Publicly available  GEN, SPEX, XRAY branches  Updated regularly  IDL and SSW installed in FermiVM for this workshop  Temporary IDL license expires August 31, 2012 August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 3

4. OSPEX  Currently handles  RHESSI spectrum and image cube  Fermi CSPEC, CTIME, and LAT PHA2 or LLE  XSM  SOXS  MESSENGER  YOHKOH WBS  User-provided spectrum  Any time-ordered count spectrum data with response information can be added August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 4

5. OSPEX negatives  Requires purchase of IDL license  Analyze single data source  Simultaneous fitting of multiple instruments (or detectors) is planned  Chi-square fitting only  Problematic with low count rates  C-statistic fitting is planned August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 5

6. OSPEX Positives  Any OS  Graphical interface, or command line, or BOTH  Multiple fit analysis intervals  View and save results  Save setup script  PLOTMAN simplifies graphic manipulations  Flexible design allows for adding new data easily  SSW – view/analyze Fermi event as observed by other instruments August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 6

7. OSPEX documentation  OSPEX User Guide OSPEX User Guide  What’s New in OSPEX What’s New in OSPEX  OSPEX Object Parameter Tables OSPEX Object Parameter Tables  Available via Help button on OSPEX GUI August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 7

8. OSPEX Steps 1. Start OSPEX 2. Select Input 3. Define background time interval(s) 4. Define analysis time interval(s) 5. Select spectral model component(s) 6. Fit intervals 7. View results 8. Save results and script 1. Run script and import results 2. View results August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 8

9. Starting OSPEX Start SSWIDL  sswidl  sswidlde & o = ospex() August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 9

10. Using OSPEX  o is reference to ospex object  Use o at command line or through GUI simultaneously  Click Refresh button in widgets to display changes from command line August 22-23, 2012Fermi Solar Data Analysis Workshop at GSFC kim.tolbert@nasa.gov 10
