Build Swift-XRT products.

Using this form you can build an XRT light curve, spectrum or enhanced position of any object observed by Swift. Full documentation for this process is given in the online documentation. If you enter your e-mail address on the form below, an e-mail will be sent to you when the processing is complete. Fields marked with a * are mandatory.

This interface is not intended for GRBs (which are processed automatically), so the default binning method is to use bins of constant duration.

This service is designed for point-sources only. Results for extended sources may be incorrect.

There are still open issues related to the analysis of Swift-XRT data. Please read the XRT digest pages before drawing conclusions from the products you generate here.
