libprofit is a low-level C++ library that produces images based on different luminosity profiles.

libprofit currently supports the following profiles: sersic, coresersic, moffat, ferrer, king, brokenexp, sky and psf. With time we intend to add more profiles to the library. Users can also provide their own profiles.

For more information read libprofit's documentation.

libprofit's Issues

No library header

Hello, when I make install libprofit, the library header file (library.h) never gets made. This causes an interruption when I try to setup pyprofit, since library.h is included in profit.h, which it tries to read.
I tried different C/C++ compilers to the same end. How can I resolve this?

Running examples

Hello,

I am trying to run the usage.py example script that comes with the pyprofit code. I am getting the following error

error: axrat > 1, must have axrat <= 1

Is scipy allowing the parameter to veer outside its allowed range or is there some problem with my code. I am very keen to use Gaussians in line with the advice of Hogg and Lang 2012. It currently doesn't seem as if you include gaussian profiles. How might I add this to the C++ library? Would it be possible to define the psf analytically in order to take advantage of convolution speed up associated with mixtures of gaussians?

I am just starting to try and use pyprofit instead of my clunky Galfit wrapper which necessitates writing feedme files and then reading fits output files which is less that ideal.

Many thanks,
