I've not really looked at the page yet; but already I know that I need HELP! WebSpec is a WWW interface for the X-ray spectral fitting package, XSPEC. Iit can be used to simulate spectral data for a variety of X-ray missions/instruments. Choose a Mission/Instrument XMM EPIC MOS1 CCD with thin filter XMM EPIC MOS1 CCD with medium filter XMM EPIC MOS1 CCD with thick filter XMM EPIC MOS2 CCD with thin filter XMM EPIC MOS2 CCD with medium filter XMM EPIC MOS2 CCD with thick filter XMM EPIC pn CCD with thin filter XMM EPIC pn CCD with medium filter XMM EPIC pn CCD with thick filter Chandra ACIS-I on-axis Chandra ACIS-I 2' off-axis Chandra ACIS-I 4' off-axis Chandra ACIS-I 6' off-axis Chandra ACIS-S on-axis Chandra ACIS-S 2' off-axis (away from ACIS-I) Chandra ACIS-S 2' off-axis (toward ACIS-I) Chandra HEG (order 0) Chandra HEG (order 1) Chandra HEG (order -1) Chandra HEG (order 2) Chandra HEG (order -2) Chandra HEG (order 3) Chandra HEG (order -3) Chandra LETG/ACIS (order 0) Chandra LETG/ACIS (order 1) Chandra LETG/ACIS (order -1) Chandra LETG/ACIS (order 2) Chandra LETG/ACIS (order -2) Chandra LETG/ACIS (order 3) Chandra LETG/ACIS (order -3) Chandra LETG/HRC (order 1) Chandra LETG/HRC (order -1) Chandra LETG/HRC (order 2) Chandra LETG/HRC (order -2) Chandra LETG/HRC (order 3) Chandra LETG/HRC (order -3) Chandra LETG/HRC (order 4) Chandra LETG/HRC (order -4) Chandra LETG/HRC (order 5) Chandra LETG/HRC (order -5) Chandra LETG/HRC (order 6) Chandra LETG/HRC (order -6) Chandra MEG (order 1) Chandra MEG (order -1) Chandra MEG (order 2) Chandra MEG (order -2) Chandra MEG (order 3) Chandra MEG (order -3) Constellation-X SXT RXTE HEXTE RXTE PCA 3 PCUs (Layer 1 only) RXTE PCA 3 PCUs (Layers 1+2+3) RXTE PCA 3 PCUs (TEST) Suzaku XIS BI (6 arcmin region at standard position) Suzaku XIS BI (6 arcmin region at HXD position) Suzaku XIS BI (uniform field) Suzaku XIS 2FI (6 arcmin region at XIS position) Suzaku XIS 2FI (6 arcmin region at HXD position) Suzaku XIS 2FI (uniform field) Suzaku HXD PIN (at XIS pointing position) Suzaku HXD PIN (at HXD pointing position) Suzaku HXD GSO (at XIS pointing position) Suzaku HXD GSO (at HXD pointing position) Swift XRT Photon Counting Mode (Grade 0) Swift XRT Photon Counting Mode (Grades 0-12) Swift XRT Windowed Timing Mode (Grade 0) Swift XRT Windowed Timing Mode (Grades 0-2) Swift BAT on-axis, imaged (background-subtracted) Swift UVOT U Grism Swift UVOT V Grism ASCA GIS ASCA SIS BeppoSAX LECS BeppoSAX MECS BeppoSAX PDS BeppoSAX HPGSPC ROSAT PSPC Specify the desired model expression by clicking on the proper combination of components and operators.
