What is the proper way to specify a field without a unit? I though unit: "1" would be fine, but in the latest nightly (1.6), that unit is being listed on the color table:
From the netCDF standard document:
Units are not required for dimensionless quantities. A variable with no units attribute is assumed to be dimensionless. However, a units attribute specifying a dimensionless unit may optionally be included. The Udunits package defines a few dimensionless units, such as percent, but is lacking commonly used units such as ppm (parts per million). This convention does not support the addition of new dimensionless units that are not udunits compatible. The conforming unit for quantities that represent fractions, or parts of a whole, is "1".
If this is a valid way of specifying "no unit", then shouldn't McIDAS-V convert the unit of "1" to no unit before displaying on the color table?
