The default Mathematica builder function newPsy[tdb] for Webel MPsy objects requires a mandatory dry bulb temperature 'tdb' Quantity, and one (only) of the following options must be provided:

$opt$psy$r: The relative humidity 'r' as a Real
$opt$psy$w: The humidity ratio 'w' as a Real
$opt$psy$twb: The wet bulb temperature 'twb' as a Quantity

The provision of pressure 'p' Quantity as option $opt$psy$p is not mandatory, it defaults to the atmospheric pressure at sea level.
