Next steps:
Thorough calibration with SDO results.
Unattenuated frame selection: median of several?
Find more events to examine!
Summary:Mass determination technique of eruptive
filament material in development.
Demonstrated the applicability of the method to SWAP data.
Currently working on ways to improve the accuracy of the results from SWAP data.
