Depend variables require the SIZES and VALUE_TYPE parameters to be set, and should take the UNITS, SI_CONVERSION and DATA parameters in the same way as a data variable. They should take a LABLAXIS attribute to provide labelling information specific to that index. A DELTA_PLUS and DELTA_MINUS attribute is also required to establish bin boundaries for DEPEND_i.
Depend variables do not, themselves, take Depend variables to describe the arrays.
For example, an array whose first dimension is energy in 7 bins might have
DEPEND_1 = EnergyBins
and the associated variable, EnergyBins takes the form
START_VARIABLE = EnergyBins
DELTA_PLUS = 0.05
DELTA_MINUS = 0.05
SCALING = ``linear''
DATA = 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7
UNITS = ``keV''
LABLAXIS = ``E''
SI_CONVERSION = ``1.602e-16
J''
END_VARIABLE = EnergyBins
