Transcript summary of session

Source identification and
characterization, catalog contents
• Catalog contents – issues like “What is the
purpose of the catalog?”
– Derived from the gamma-ray data: Energy bands,
source location contours, upper limits, variability
index, significance, flux history, spectral index, and
source name
– Test for ‘extendedness’
• Correlative – coincidences with sources in
selected other catalogs - not source
identification or discovery of new source classes,
although sources known to be, e.g., pulsars are
flagged as such
