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 VHE observations on LAT targets. Somwhat 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 on galactic LAT sources | Source identification without an "a prior" on the LAT spectrum. We dont know if there are IC-reprocesses components, distinct from LAT energetic coverage. |
13 | Monitoring Repeated monitoring of not firmly identified galactic VHE/GeV source associations | Investigate potential variability to aid in source identifcation. |
