UVS Characteristics & Performance
| Feature | Characteristic or Performance | Driving Requirement |
| Spectral Range: |
68-210 nm | Get H2 bands & H Ly series |
| Spectral Res.: |
~0.4-0.6 nm (point source) ~1.0-2.6 nm (extended source) |
Get color ratios (get CH4 and look for C2H2 absorption |
| Spatial Res.: |
~0.1° (125 km from 1 RJ above the aurora) | Get better than HST resolution |
| Effective Area: |
0.6 cm2 @ 121 nm, 0.07 cm2 @ 170 nm | Get >100 kR auroras |
| Feature |
Characteristic or Performance | |
| Mass & Power |
21.6 kg & 9.3 W | |
| IFOV: |
0.2° x 2.5° + 0.025° x 2° + 0.2° x 2.5° → “dog-bone” shape | |
| Field of Regard: |
360° x 60° (2 RPM & ±30° from spin plane → half the sky is accessible) | |
| Design: |
Off-Axis Primary telescope / Rowland circle mount spectrograph | |
| Detector Type: |
Curved 2-D MCP (solar blind), Csl photocathode, cross delay-line (XDL) readout, 24 bits/event; 2048 spectral (perpendicular to slit) x 256 spatial (parallel to slit) x 32 (PHD) | |
| Radiation Mitigation: | Shielding (contiguous 100 mils Ta, ~4 at the detector, rejects energetic electrons <3 MeV); Pulse Height Distribution (PHD) thresholding | |
