Dear All
Another one is NerikPhotometry that has been written by Eric Rumbo. It is 
not on the web at present but he sent it to me on a disk. I have tried it 
out on the challenge files.

Below is a copy of the post by Bernard on IIS here in Oz that pointed it out 
to me.

Nerik Photometry & Period software

--------------------------------------------------------------------------------

Just back from the RASNZ Wellington conference, and workshops, where Eric 
Rumbo (he wasn't present) had a display board presentation of his 'Nerik 
Photometry' and 'Nerik Period' software package ... plus a bunch of free 
DVDs, which went fast! I've only had a brief play with them using the 
included sample data and my initial impressions are that they are good. One 
of the nice photometry features is that the aperture measuring annulus can 
me divided into 16 (18?) segments which can be individually deselected if 
any contain unwanted star(s). The whole process, including deriving the 
magnitudes of up to 999 stars in every image for multiple images, is all 
automated and reminds me of the Canopus program.

The package also includes a separate 'Nerik Period' program which produces 
the period of any regular variable object, using FFT, and it work well.

I've not found any website for the Nerik software but if you are interested 
in getting hold of a copy (which I assume are free) you can contact Eric at 
erumbo AT bigpond DOT net DOT au.

>    * handling of optical, near-infrared and mid-infrared data
>    * single- and multichip (mosaic) cameras are handled, including even

>    * automatic astrometric and photometric calibration using scamp or
> astrometrix
>    * stand-alone tools in C/C++, no black boxes
>    * fast (fully parallelised for multi-core and cluster architectures)
>    * comes with a graphical user interface
>    * in its current version, THELI supports more than 35 professional
