Session 9. Analysis of Grating Data

Workshop, Monday, November 6, 2000, 7:30-9:30pm, 6:30-8:30pm, Pago Pago Ballroom

This workshop will focus on how to get a flux-calibrated spectrum and what instrumental and calibration effects and choices users should be aware of in the final spectrum. Trade-offs, known calibration issues, and other issues will be discussed. In addition, a short talk at the end will introduce some of the new high-resolution spectral analysis models and tools that are available. This workshop features talks from scientists directly involved in the calibration of the instruments and in creating the latest atomic models.

Specific talks will include:

Chandra HETG data issues (Herman Marshall)

Chandra LETG data issues (Jeremy Drake)

XMM/Newton RGS data issues (Andrew Rassmussen)

Atomic models for high-resolution X-ray data (Randall Smith)

Some of the issues that will be discussed include:

-- Instrumental line shape response

-- Wavelength accuracy

-- Background issues

-- Order sorting issues

-- Comparing/summing plus and minus orders

-- Effect of changing extraction region on spectra

-- Identifying and fitting isolated and blended emission lines in data

-- Finding and applying relevent atomic data and references
