Definition of the STEP PHA buffers at the date of the launch of the mission.
| PHA buffer # | Sensor channel | Description |
|---|---|---|
| 0–2 | Single hits | |
| 3 | 7 keV < E < 9 keV (Cu X-ray line) | |
| 4 | IC | E > 70 keV (MIPS) |
| 5 | E < 2 keV (noise) | |
| 6 | Wrong pixel size | |
| 7 | Multiple hits | |
| 8–10 | Single hits | |
| 11 | 7 keV < E < 9 keV (Cu X-ray line) | |
| 12 | MC | E > 70 keV (MIPS) |
| 13 | E < 2 keV (noise) | |
| 14 | Wrong pixel size | |
| 15 | Multiple hits | |
Notes. It is expected that buffers 6 and 14 will remain empty, unless there is a problem with the configuration or data processing of the sensor.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
