XRT Cadence Estimates
(Extracted from Yoshifumi Shimizu's presentation at SOT17 @ NAOJ,
17-April-2006).
The total data rate of 400 kbps (about 15 downlink/day) is assumed. SOT,
XRT, and EIS usually share this data rate in the ratio of 70%, 15%, and
15%. XRT image data is 12 bit/pixel and may be compressed to about 6
bit/pixel by DPCM.
Typical data rate for XRT ~ 600 k pixel per minute.
- Example 1: Continuous Observation (576 k pixel/min)
- 384" x 384", 1"-resolution, 30sec-interval of a filter
pair.
- Example 2: High-Speed Observation (576 k pixel/min)
- 384" x 384", 1"-resolution, 5sec-interval of a filter
pair, 10min-continuous observation and 50min
intermission.
- Example 3: Combination of FFI and PFI (586 k pixel/min)
- 384" x 384", 1"-resolution, 40sec-interval of a filter
pair.
- 2048" x 2048", 4"-resolution, 200sec-interval of a filter
pair.
