The photos library simulates qed photon radiative corrections in electromagnetic decays. the library is universal; it allows for easy interface with any program generating decays of any particle. it can be used to estimate the size of the qed bremsstrahlung in leading-logarithmic approximation. the proper soft photon behavior is also reproduced.

note that in order to compile and link programs against this library, you must also install the libphotos202-dev package.
