Resolution level of the data.
The value can be entered in of three ways:
May be entered as a string or any numeric type for equality matching
May be a string of the format ‘(min) - (max)’ for range matching
May be a string of the form ‘(operator) (number)’ where operator is one of: lt gt le ge < > <= >=
This attribute is currently implemented for SDO/AIA and HMI only. The “resolution” is a function of the highest level of data available. If the CCD is 2048x2048, but is binned to 512x512 before downlink, the 512x512 product is designated as ‘1’. If a 2048x2048 and 512x512 product are both available, the 512x512 product is designated ‘0.25’.
