Phoranso: Any input appreciated

[Grady Boyce]

Hello all.

We have recently started using Phoranso for our photometric reductions. Previously I had been using another piece of software, but this seems quite powerful.

Was wondering what feedback any other Phoranso users have about this product and if it will become your 'go to' photometric calibration and reduction software.

Thanks, Grady

Hi Grady,

Just to follow up here after our conversation on zoom the other day regarding what people use to do photometric calibration and reduction. Most professionals and those that learn how to do this at an undergraduate or above level will most likely learn how to use python do to this work. Please see below for the links to the various packages, reference guides, and tutorials on how to do this

Python, Astropy is the hub of most things to do with astronomy. The homepage can be found here

tutorials on how to use astropy and its various functions can be found here

the guide on how to reduce images (flats, darks, bias etc) can be found here

Once you have calibrated images, the best way to do photometry is to use the photutils package, a package or add-on to AstroPy. This goes through how to estimate your background, how to find sources, how to do aperture photometry, how to do PSF photometry and more

for most of the work folks do, the aperture photometry section is probably the most useful section to dig into.
