This is I(Q). The client has to analyse the dimensions of I(Q). Often, multiple I(Q) for various environment conditions are measured; that would be the first dimension. Q can be multidimensional, this accounts for the further dimensions in the data

variable: (required) NX_NUMBER (Rank: 1, Dimensions: [nVars])

@varied_variable: (required) NX_CHAR

The real name of the varied variable in the first dim of data, temperature, P, MF etc…

qx: (required) NX_NUMBER (Rank: 1, Dimensions: [nQX])

Values for the first dimension of Q

qy: (required) NX_NUMBER (Rank: 1, Dimensions: [nQY])

Values for the second dimension of Q
