### SCUBA2_PHOTOM

Perform aperture photometry on SCUBA-2 images

#### Description:

Perform aperture photometry on SCUBA-2 images using the chosen method. There are three methods:

Use the Starlink AUTOPHOTOM package to perform aperture photometry using the given aperture and annulus dimensions (default). The default aperture radius is 30 arcsec.Calculate the sum within a given aperture, correcting for any DC offset by analyzing the image outside the aperture.As above, but estimate the background offset using an annulus (see the parameters ANNULUS_INNER and ANNULUS_OUTER below).The results are written to a log file called log.flux.

#### Notes:

• It is assumed that the images can be used as is with no further requirement for cropping or background removal.

• Input data should be calibrated - the recipe does not apply any calibration.

#### Available Parameters :

##### ANNULUS
Flag to denote whether to use an annulus for background estimation.
##### ANNULUS_INNER
Inner radius for annulus as a multiplier of the aperture radius.
##### ANNULUS_OUTER
Outer radius for annulus as a multiplier of the aperture radius.
