This schema describes telemetry data by inheriting schema elements from XDF using a redefine. allow for I758 type floats. Extends xdf dataFormat types to include binaryTime datatype for holding date and time in binary representation width in bits List of time units present, eg "year month day hour". If just "day" or "second" then it is an offset and the fiducialTime is needed. date and timeof zero time if it is represented as an offset. Extend XDF binary Integers to allow for ones-complement and sign-magnitude Extend XDF structure to include: system, subsystem, PI, collaborator, and rights. extend arrayType to include I785 floats types and integer twos-complement and sign-magnitude. Setting it here means it is not needed in all of the individual fields. But, setting either of these in a field would over-ride the setting here. extend noteType with lo(hi)Inclusive(Exclusive), bit, and applyToConverted attributes. lo(hi)Inclusive(Exclusive) which sets the range on values for which the text in note applies. text in note applies to the nth bit, where n is set here. Need to first apply conversion before determining if note applies to value (if this is set to true) Like columns in tables, this holds header info (name, units, dataFromat) of a single data type. This type has both extensions (start,end,default, min,max,conversion) and restrictions on @class/enumeration. Unique identifier for field Allow clone of field metadata from another array. Each discipline should define enumeration of field/types. If complex numbers are needed, simply add a fieldAxis with 2 fields, a real one and an imaginary one N-d vector fields are handled by N unitDirection fields. If the components are along the axes use ref to refer to axisIdRef. Root Element for this telemetry schema. Project or Mission Title Main system or spacecraft source of data Subsystem within main system source of data principle investigator associated personnel to project Statement of data copyrights ownership and restrictions sampled point on curve that provides conversion from data units to physical units The output component of the point. The input component of the point. Holds various ways to convert from data units to physical units spline fit through a set of curvePoints Order of spline fit. order=1 is piecewise linear, order=2 is piecewise parabolic, order=3 is cubic spline. conversion curve is generated by polynomial. The coefficients are procided here as a list. start bit or byte of a field from beginning of record end bit or byte of a field from beginning of record minimum value of field. If no @type then this is minimum possbile If present and set to yellow, then this is the minimum yellow level. Same if red. determines whether to apply min value to raw or to converted values. see annotations in min element Default value to apply when noData value is set.
