echo_intensity_test_quality_flag 1 [UUUU] A quality flag that reports the result of the Echo Intensity test, which checks that beams in adjacent bins do not differ by more than an operator-provided amount. The linkage between the data variable and this variable is achieved using the ancillary_variables attribute. There are standard names for other specific quality tests which take the form of X_quality_flag. Quality information that does not match any of the specific quantities should be given the more general standard name of quality_flag.
