FILES CORRESPONDING TO REQUIREMENT AND GOAL CONFIGURATIONS FOR THE LAD:
| File | Notes | File Packs |
| LOFT_Requirement_v4.rmf | RMF file assuming LAD current capabilities ("requirement") | All requirement files |
| LOFT_Requirement_v4.arf | ARF file assuming LAD current capabilities ("requirement") | |
| background_Requirement_v4.bkg* | Background estimated assuming LAD current capabilities ("requirement") | |
| LOFT_Goal_v4.rmf | RMF file assuming LAD foreseen capabilities ("goal") | All goal files |
| LOFT_Goal_v4.arf | ARF file assuming LAD foreseen capabilities ("goal") | |
| background_Goal_v4.bkg* | Background estimated assuming foreseen LAD capabilities ("goal") | |
*For the background v4.0, the properties of the collimators were changed with respect to those reported in the LOFT proposal to the Cosmic Vision call (see HERE). For further details we refer the reader to the LAD guide.
FILES CORRESPONDING TO SINGLE-ANODE EVENTS ONLY IN THE REQUIREMENT AND GOAL CONFIGURATIONS FOR THE LAD:
| File | Notes | File Packs |
| LOFT_Requirement_single_v4.rmf | RMF file for single-anode events only assuming the LAD current capabilities ("requirement") | All single events requirement files |
| LOFT_Requirement_single_v4.arf | ARF file for single-anode events only assuming LAD current capabilities ("requirement") | |
| background_Requirement_single_v4.bkg* | Background estimated for single-anode events only assuming LAD current capabilities ("requirement") | |
| LOFT_Goal_single_v4.rmf | RMF file for single-anode events only assuming LAD foreseen capabilities ("goal") | All single events goal files |
| LOFT_Goal_single_v4.arf | ARF file for single-anode events only assuming LAD foreseen capabilities ("goal") | |
| background_Goal_single_v4.bkg* | Background estimated for single-anode events only assuming foreseen LAD capabilities ("goal") | |
*For the background v4.0, the properties of the collimators were changed with respect to those reported in the LOFT proposal to the Cosmic Vision call (see HERE). For further details we refer the reader to the LAD guide.

(Consult also the LOFT Instruments page for more details on the WFM)
|
| File | Notes | File Packs |

| wfm_crab.xcm | Example XSPEC script file that simulates the spectrum obtained from a 1 ks observation of the Crab |
* We recommend the user to read the "User Guide" provided above before making use of these files.
Please use all the above files carefully.
All the assumption and approximations used to obtain them are relying on preliminar study of the instruments capabilities.
