There is a separate chapter for the EIT science planners . In any case, you should ensure that the EIT science planner during the dates of your observations should be fully aware of the full extent of the observing plans, and you should remain in contact with the planner until the observations are complete. The numbers preceding the period denote the date of the observation - yyyymmdd. EFZ' denotes EIT Fits Level Zero data. The total exposure time of the image.
Exposure times vary for different filters, and for the type of solar activity.
A 1024 by 1024 pixel image is thus reduced to the size of a 512 by 512 image. A partial image will have a smaller range of pixels, and will consist of a 2-dimensional array of smaller size. It is usually available about a month after the observing time. You should always try to use level zero data. The web catalog interface will provide a list and brief description of the data obtained over a range of dates.
