How do I convert my SPIRE data from Jy/beam to Jy/pixel?

Answer supplied by Ivan Valtchanov:

To do the conversion, you should use the pipeline beam area as provided in the SPIRE Data Reduction Guide, table 6.7, i.e. (465.35, 831.27, 1804.31) arcsec^2 at (250, 350, 500) microns, in order to convert your image from Jy/beam to Jy/pixel.

Within the Herschel Interactive Processing Environment (HIPE): you can use the task, convertImageUnit():

newImage = convertImageUnit(image=my250_image_in_Jy_per_Beam, newUnit='Jy/pixel',beamArea=465.35)

You can find out more about this process in the useful Herschel Science Centre short videotutorial on SPIRE Photometer: Aperture photometry. You can find the videotutorial, here:
