Data Quality: 8.0
8.0 is calculated from all Active Region Observation datasets:Instrument | Reduction Status |
---|---|
ROSA G-band | Level-0 |
ROSA 4170Å | Level-0 |
ROSA Ca K | Level-0 |
Zyla 6563Å | Level-0 |
FIRS Slitjaw | Level-0 |
FIRS 10830Å | Level-0 |
HSG 6302Å | Level-0 |
HSG 8542Å | Level-0 |
HSG 5876Å | Level-0 |
HSG slitjaw | Level-0 |
Data levels are defined as follows:
There were 1 different observing series on this date. Observing and calibration windows covered the following ranges:
Seeing parameters are calculated from Level-0, unprocessed data, before speckle reconstruction. The "median" and +/- 1-sigma images below are calculated from the Helmli-Scherer mean (HSM) for ROSA, and the Median Filter Gradiant Similarity (MFGS) metric for Zyla. These metrics (and others, such as the RMS, and mean of the image) are calculated for the full observing day. HSM and MFGS are the most sensitive to unknown atmospheric conditions, however, the HSM is faster and tends to perform better with photospheric data, while MFGS performs better with chromospheric structures.
