An archive of Chandra observations of regions of star formation (ANCHORS)

Brad Spitzbart (SAO)

ANCHORS is an archive of Chandra observations of regions of star formation. It is designed to aid both the X-ray astronomer with a desire to compare X-ray datasets and the star formation astronomer wishing to compare stars across the spectrum. We are completing a Phase 2 repro cessing of all datasets (80+ observations, 50+ distinct fields) to provide improved analysis and greater uniformity. The data consist of X-ray source prop erties including position, net count rates, flux, hardness ratios, lightcurve statistics and plots. Spectra are fit using several models, with final parameters and plots recorded in the archive. Multi-wavelength images and data are cross-linked to other resources such as 2MASS and SIMBAD. We will demonstrate the system, examine scientific pilot studies using the archive, and solicit users' feedback. This project is supported by Chandra archival grant AR5-6002A and NASA contract NAS8-39073.
