We present the observations, data analysis methodology, and tabulated results from the Chandra Orion Ultradeep Project (COUP). COUP is based on a single nearly-continuous 850 ks pointing towards the Orion Nebula obtained in January 2003. Over 1600 young stars are detected. Data preparation includes correction for charge transfer inefficiency and subpixel event repositioning. Source detection is based on two wavelet-based search algorithms optimized for maximum reduction of background. For each source, we perform data extraction, pileup correction, spectral and variability analysis, and broad-band luminosity determinations using the sophisticated semi-automated IDL-based ACIS Extract (AE) package. Our treatment of photon pileup using annular extraction regions is effective for both lightly and heavily piledup sources. The AE data products efficiently provide detailed and comprehensive information for point sources in ACIS fields.
COUP is supported by Chandra grant SAO GO3-4009A (Feigelson PI). ACIS Extract is available at http://www.astro.psu.edu/xray/docs/TARA/ae_users_guide.html.
