atmosphere.getNonDispersiveDryPhaseDelay - Function

4.1.1 get the integrated nondispersive dry Atmospheric Phase Delay
Description

Function to retrieve the integrated dry Atmospheric Phase Delay (NonDispersive part) along the atmospheric path corresponding to the 1st guess water column.

Arguments


Inputs
nc	Channel number (0-based; defaults to reference channel)
	allowed:	int
	Default:	-1
spwid	Int standing for spectral window id (0-based)
	allowed:	int
	Default:	0

Returns
Quantity

Example

for spwid in range(numSpw):
        numCh = at.getNumChan(spwid)
        print "Spectral window ", spwid, " has ", numCh, " frequency channels"
        for n in range(numCh):
                freq = at.getChanFreq(n, spwid)
                print "Total Dispersive Dry Phase Delay at ", freq.value, freq.units, " for 1.0 air mass: ", (at.getDispersiveDryPhaseDelay(n,spwid).value)/(w.value),
" degrees per mm of water vapor (", ((100*at.getDispersiveDryPhaseDelay(n,spwid).value)/(w.value))/(at.getNonDispersiveDryPhaseDelay(n,spwid).value/w.value), "% of the Non-dispersive one )"
