Workshop : Error Treatment

How are systematic errors included in spectral analysis ?
XSPEC’s SYSERR is not the right thing to do.

Wilms’s procedure..

Detection of broad Fe lines above badly determined continua.

Some problems are more badly affected by systematic errors. Users should be provided with clear advice about which types of scientific analysis are likely to be affected by systematic errors.

What are systematic errors ? Herman’s definition.

Supply alternative calibration files.

Drake’s talk and the possibility to make it available more widely..

It is the calibrator’s responsibility to try to prevent erroneous results. The story of the HRC jet. No new mistaken physics, please.

Quoting systematic errors is too simplistic…

Reliability of spectral models in XSPEC and elsewhere..

Discrepancy of X-ray column densities.

Role of simulations ?

Different types of errors : energy is what we have mainly been talking about, but there are also imaging and timing errors to be considered.
