Limited Engineering Struct: This type is used for engineering data fields for which there are known "yellow" limits
| Field Name | Type | Explanation |
| min | 32-bit floating-point | Minimum value field takes on in granule (not valid when num_in = 0) |
| max | 32-bit floating-point | Maximum value field takes on in granule (not valid when num_in = 0) |
| mean | 32-bit floating-point | Mean of in-range values field takes on in granule (not valid when num_in = 0) |
| dev | 32-bit floating-point | Standard Deviation of in-range values field takes on in granule (not valid when num_in = 0) |
| num_in | 32-bit integer | Count of in-range values field takes on in granule |
| num_lo | 32-bit integer | Count of out-of-range low values field takes on in granule |
| num_hi | 32-bit integer | Count of out-of-range high values field takes on in granule |
| num_bad | 32-bit integer | Count of occassions on which field takes on invalid flag value (-9999) in granule |
