image.convertflux - Function

1.1.1 Convert flux density between peak and integral
Description

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

Inputs
value	Flux density to convert. Must be specified.
	allowed:	any
	Default:	variant 0Jy/beam
major	Major axis of component. Must be specified.
	allowed:	any
	Default:	variant 1arcsec
minor	Minor axis of component. Must be specified.
	allowed:	any
	Default:	variant 1arcsec
type	Type of component. String from Gaussian, Disk.
	allowed:	string
	Default:	Gaussian
topeak	Convert to peak or integral flux desnity
	allowed:	bool
	Default:	true

Returns
anyrecord

Example

"""

p2 = ia.convertflux(i1, major=’30arcsec’, minor=’10arcsec’, topeak=T)
print ’peak, integral, peak = ’, p1, i1, p2
