Further Steps/Improvements
o
o
Handling of Data Gaps
Handling of long-duration Flares:
splitting into separate flares, if the intensity has more than one peak
o
Subflares: include into the list, if they are very bright
o
Movie for each Flare
o
Active Region numbers for Flares: for easier identification
o
Update of Flare
reaches a higher importance class
