Number | Item Wished from HESS | Rationale |
|---|---|---|
1 | Information about telescope performance and source observability, to the extent HESS is willing to share (Olaf's list - probably expand into several items here) | Allow estimates of LAT ability to add useful data |
2 | Information about data analysis plans and procedures, to the extent HESS is willing to share (Olaf's list - probably expand into several items here) | Help determine comptability with LAT approaches |
3 | Observing schedule | LAT can make sure quick results on HESS target sources are available |
4 | Derived detections or upper limits (from archive) for LAT sources with hard enough spectra to be of interest | Constrain source models and/or time variability. |
5 | Tool to show visibility/sensitivity for any sky position at any time | If LAT sees something (like a flare) of interest, this tool would determine whether HESS should be notified. In addition, this information might determine whether a pointed Target of Opportunity for GLAST might include HESS. |
6 | Notifications of observed transient events | If HESS sees a transient event we could decide whether this should trigger a pointed Target of Opportunity. This kind of information is traditionally shared among VHE observatories and could be useful for us as well. |
7 | A procedure to obtain science products (lightcurves and skymaps) adapted to GLAST time and spatial resolution | Having comparable science products (e.g. in terms of rebinning) optimizes the comparison of data sets. |
8 | Time sharing on HESS observations | HESS could open a fraction of its observation time for GLAST-LAT initiated projects (5%? more? with AO Sept. 2007?). GLAST science data products on these projects would be shared with the HESS collaboration. |
9 | Coordinated observation campaigns | A specific and instantly applicable policy to initiate request VHE observations on LAT targets. Somwhat Somewhat similar to (8), but data sharing may or may not be the determining issue. Min. goal: Back-to-back submissions from both collaborations. Max. goal: see (8). This gurantees that at least data will be taken on a request source, even if not ad hoc shared. |
10 | Extended VHE source templates | Actual data products of extended VHE-sources to be used as morphology templates in LAT high-GeV analysis. |
11 | X-calibration | Joint approach in methodology, feasibility and application. Long term issue. |
12 | Upper limits in regions of VHE coverage | Source identification without an "a prior" on the LAT spectrum. We dont know if there are IC-reprocesses components, distinct from LAT energetic coverage. Even sources with pronounced GeV cutoff may appeal. Ideal: occasionally updated upper limit map. |
13 | Repeated monitoring of not firmly identified galactic VHE/GeV source associations | Investigate potential variability to aid in source identifcation. |
