Serendipitous Source Extraction

If you find an observation with a source which has a visible grating spectrum which has not been extracted, you may give us the information in the following form and the extraction will typically appear within one or two days. Please do a Cone Search first to verify that the source is not in the current catalog.

Enter Chandra ObsID.

Obsid:

For coordinates, enter sky pixels (X and Y) or celestial coordinates (RA and Dec). RA and Dec may be given in decimal degrees (dd.dddd, [+/-]dd.dddd) or in sexagesimal notation, (hh:mm:ss.sss, [+/-]dd:mm:ss.sss).

Exact? If unchecked, we will run a source-detection algorithm to determine the source centroid.
Otherwise, we will extract on the given coordinates.

Enter object name. Please use the common name or primary SIMBAD name (if available). If there is no identification, use "unkown" and we will follow the IAU-approved CXOU convention. Identifier name is case insensitive.

Is there anything non-standard we should consider when extracting the spectrum?
