ACIS Extract (AE) is an IDL program that assists the observer in performing the many tasks involved in analyzing the spectra of large numbers of point sources observed with the ACIS instrument on Chandra. Notably, all tasks are performed in a context that may include multiple observations of the field. Features of AE and its several accessory tools include refining the accuracy of source positions, defining extraction regions based on the PSF of each source in each observation, generating single-observation and composite ARFs and RMFs, applying energy-dependent aperture corrections to the ARFs, computing light curves and K-S tests for source variability, automated broad-band photometry, automated spectral fitting and review of fitting results, and compilation of results into LaTeX tables. A variety of interactive plots are produced showing various source properties across the catalog. This poster details the capabilities of the package and shows example output. The code and a detailed users' manual are available to the community at http://www.astro.psu.edu/xray/docs/TARA/ae_users_guide.html.
Support for this effort was provided by NASA contract NAS8-38252 to Gordon Garmire, the ACIS Principal Investigator.
