Number | Item Wished from HESS | Rationale | |
---|---|---|---|
1 | Observing schedule | Enable LAT collaboration to react in a timely way on particular objects of interest on the basis of LAT observations. Community service for | |
2 | Observing history | Enable LAT collaboration to check if VHE exposure is present. | |
3 | 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. | |
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. | |
Information about telescope performance/sensitivity, | Enable LAT collaboration to estimate usefulness of (any/further) | ||
5 | TInformation about data formats and open-source analysis tools. | Enable LAT team to determine the best approaches for common analysis with the LAT FITS format data and FTOOLS- and ROOT-based analysis. | |
6 | 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. |

LIST 2 - Science-Oriented Topics
Number | Item Wished from HESS | Rationale |
---|---|---|
1 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 2 | Coordinated observation campaigns | A specific and instantly applicable policy to request VHE observations on LAT targets. 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 requested source, even if not ad hoc shared. |
10 3 | Extended VHE source templates | Actual data products of extended VHE-sources to be used as morphology templates in LAT high-GeV analysis and MWL modeling. |
11 4 | X-calibration | Joint approach in methodology, feasibility and application. Long term issue. |
12 5 | 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. |
14 | VHE source spectra & lightcurves | Detailed MWL modeling of a few (t.b.d.) dedicated LAT/VHE objects. |
15 | Personal point(s) of contact | For efficient working on a well-defined scientific topic (MWL data analysis, joint proposal planning, coordinated observation campaigns etc. ) a personal representative for easy, knowledgeable, and daily exchange. Topically distinguishable (via working groups?) |
