atmosphere.getNonDispersivePhaseDelay - Function

4.1.1 get the integrated zenith H2O Atmospheric Phase Delay (Non-Dispersive part)

Description

Get the integrated zenith H2O Atmospheric Phase Delay (Non-Dispersive part) for the current conditions, for channel number nc of spectral window spwid.

Arguments


Inputs
nc	Channel number (0-based; defaults to reference channel)
	allowed:	int
	Default:	-1
spwid	Int standing for spectral window id (0-based). The value must be >= 0.
	allowed:	int
	Default:	0

Returns
Quantity

Example

w = at.getUserWH2O()
numSpw = at.getNumSpectralWindows()
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 Phase Delay at ", freq[’value’][0], freq[’unit’], " for 1.0 air mass: ",\
                      (at.getDispersivePhaseDelay(n,spwid)[’value’][0])/(w[’value’][0])," degrees per mm of water vapor (",\
                      ((100*at.getDispersivePhaseDelay(n,spwid)[’value’][0])/(w[’value’][0]))/(at.getNonDispersivePhaseDelay(n,spwid)[’value’][0]/w[’value’][0]),\
                      "% of the Non-dispersive one )"
