Information and discussions about LAT common interests with the TeV community
Relevant VHE experiments
| Name | Type | Ethresh (1) |
|---|---|---|
| H.E.S.S. | Imaging Atmospheric Cherenkov | 120 GeV |
| VERITAS-4 | Imaging Atmospheric Cherenkov | 120 GeV |
| CANGAROOIII | Imaging Atmospheric Cherenkov | 500 GeV |
| MILAGRO | Air Shower | 400 GeV - 40 TeV (2) |
| MAGIC | Imaging Atmospheric Cherenkov | 50 GeV |
(1) We need to distinguish between anticipated threshold and achieved/documented threshold. Until then, be critical to any quoted number
(2) The threshold/energy response of a ground array like Milagro cannot easily be compared to ACTs. This interval respresents the energy range over which 90% of events from a crab-like spectrum are detected.
Experimental Issues
Optimizing variability studies
- Visibility tools proposals and tools H.E.S.S.
- * Unified VHE visibility tool
- * [LAT visibility tool]
- Alerts/transients/scheduled observations
- * VHE timetables
Analysis Issues
Spectral fitting tools
VHE sources
Collaboration & Policy Issues
The object of desire: What we ought to know about the facilities
| Facility | Object visibility/constraints | Analysis technique/data products | Comments |
| template | energetic threshold = f(dec); low threshold cuts readily available ? | shower reconstruction: which MC/version ? | |
| point source sensitivity = f(dec); public? generally applicable ? | high-level data product: gamma-ray excess-map - availability / conditions ? | ||
| extended source sensitivity = f(source size); public ? generally applicable ? | high-level data product: gamma-ray excess-map - format (root/fits) ? | ||
| energy resolution public? known dependencies ? | high-level data product: spectral data - availability / conditions ? | ||
| angular resolution public ? known dependencies ? | high-level data product: spectral data - format (xspect/root/...) ? | ||
