Definition |
An object of this DRM class specifies a <DRM Axis> that does not use a constant spacing between hash marks. |
|||||||||||||||
Example(s) |
· Data taken at times 1, 2, 5, 10, 50, and 100 seconds after some start time would be collected on a <DRM Irregular Axis>. Radiosonde data, including temperature, humidity, wind speed, and wind direction, is generally reported as a function of pressure height. Data are reported only when there is a significant change in one of the dependent variables. Accordingly, the pressure heights are captured at unpredictable, irregular intervals. They are best captured in a <DRM Irregular Axis>. |

Notes |
1 Gives the type of measurement along the axis, such as distance, pressure, or frequency. 2 Specifies the unit of measurement of the axis_type>, which shall be compatible with the requirements imposed by axis_type. If axis_type does not require a unit of measurement (for example, if axis_type requires a value_type of STRING), value_unit shall be set to EUC_UNITLESS. 3 Specifies the scale applicable to value_unit. If axis_type does not require a unit of measurement (for example, if axis_type requires a value_type of STRING), value_scale shall be set to ESC_UNI. 4 Indicates the number of “hash marks” along the axis. 5 Allows the data supplier to indicate how best to interpolate the data to points that are in-between grid points on the axis. When a <DRM Data Table> has more than one axis, the order of the interpolations is in the order of axis definitions. |
