Suggested Threads

These threads are a good place to start in the hands-on session. Beginners can get used to running CIAO, while intermediate users can look at specific types of analysis.

Beginners

• Introduction to the Data Products
• Introduction to the Data Model
• Using SAOImage ds9
• True Color Images
• Extract Spectrum and Response Files for a Pointlike Source
• Introduction to ChIPS (basic plotting)
• Sherpa: Introduction to Fitting ASCII Data with Errors
• Sherpa: Introduction to Fitting PHA Spectra

Intermediate Sherpa Analysis

• Fitting FITS Image Data
• Step-by-Step Guide to Estimating Errors and Confidence Levels
• Simulating 1-D Data: the Sherpa fake_pha Command - useful for Chandra proposal planning

Source Detection

• Overview: Detecting Sources in Imaging Observations
• Running celldetect
• Running vtpdetect
• Running wavdetect
• Using the Output of Detect Tools
• Estimate Source Counts in an Image
• Obtain and Fit a Radial Profile

Extended Source Analysis

• Extract Spectrum and Response Files for an Extended Source
• An Image of Diffuse Emission
• Weighting ARFs and RMFs: multiple sources
• True Color Images
• Obtain and Fit a Radial Profile

Grating Analysis

• The threads for extracting grating spectra and making responses (gARF and gRMF files) are grouped by detector-grating combination on the Grating Spectroscopy threads page.
• Examining Grating Spectra and Regions: PHA2 files
• Create a Color Spectrum
• Extract Coadded and Grouped Nth-Order Source & Background Spectra and ARFs
• Measuring Line Parameters with an HETG/ACIS-S Spectrum
• Measuring Line Parameters with an LETG/ACIS-S Spectrum

There is a complete list of all available threads on each website:

• All CIAO Data Analysis Threads
• All ChIPS Plotting and Imaging Threads
• All Sherpa Modeling and Fitting Threads
