HST previews are not currently working. We are investigating and apologize for the inconvenience. For image previews we suggest that you try the Aladin option, and for spectral previews the SpecView option. Links to these options are found near the bottom of the preview page. For ACS, STIS and NICMOS grism data you may find the HLA another good option.

Getting Started

The XMM optical/UV data was provided to MAST starting in 2006. Updates are obtained weekly? from the Guest Observer Facility at HEASARC. The data are accessible using the XMM Search Form. The search results page also has links to the XMM preview pages which allow individual images to be displayed as gif images or using Aladin..
