Convert flux density between peak and integral

Synopsis
convertflux(value, major, minor, type, topeak)

Arguments

value	in	Flux density to convert
		Allowed:	Quantity
major	in	Major axis of component
		Allowed:	Quantity
minor	in	Minor axis of component
		Allowed:	Quantity
type	in	Type of component
		Allowed:	String from Gaussian, Disk
		Default:	Gaussian
topeak	in	Convert to peak or integral flux desnity
		Allowed:	Bool
		Default:	T

Returns
Quantity or fail

Description

This function interconverts between peak and integral flux density for a Gaussian or Disk component. The image must hold a restoring beam.

Example

 
- im := image('in.im');
- p1 := dq.quantity('1mJy/beam')
- i1 := im.convertflux(p1, major='30arcsec', minor='10arcsec', topeak=F);
- p2 := im.convertflux(i1, major='30arcsec', minor='10arcsec', topeak=T)
- print 'peak, integral, peak = ', p1, i1, p2
peak, integral, peak =  [value=1, unit=mJy/beam] [value=0.000163961301, unit=Jy] [value=0.001, unit=Jy/beam]
