Daily Spectrogram: These plots show the daily dynamic spectrum (frequency-time diagram) of cross-power amplitude on the shorter baselines.

Daily Spectrogram Overview Plot

Raw "Interim" Database (IDB) Data: The original concept for EOVSA was to record the full-resolution data (1-s time resolution and full frequency resolution) as an "interim" database that would be further reduced in size for different applications (e.g. flares, active regions, full Sun). Then we planned to delete the IDB files due to their relatively large size--too large a data volume to archive. However, in practice the files are not too large to archive in their full resolution, given today's storage capacity, and therefore these are made available at full resolution (Click the link at right.) These are recorded in Miriad format, and hence may not be that useful for most people. Be patient after clicking the link--this is a very long list of directories, one for each available date.

Raw UDB Data: This is the same as for the IDB data, except with 1-minute time integration applied. This is typically not useful for flares, but is perfectly fine for imaging active regions and full Sun. (Click the link at right.) These are also in Miriad format, and hence may not be that useful for most people. After clicking the link, you will see a short list of directories, one for each year. However, clicking on a year takes you to a very long list of available data, so again be patient while the list loads.

CASA UDBms Data: These are CASA measurement sets for each of the UDB data files. As such, they also have one-minute integration applied. This is typically not useful for flares, but is perfectly fine for imaging active regions and full Sun. (Click the link at right.) After clicking the link, you will see a short list of directories, one for each year and month.
