FFT routines may still need some performance optimization, as
not all the functionality of the FFTW package is currently used.
Galactic coordinates are not yet calculated, but this can change
in the near future.
Currently preference is given to small sources over extended sources
if they are present near the same coordinates. It would be nice to have a good
selection criterium to include also extended sources in the final source list
if it is clear that the signal is not caused by the small scale source.
More work has to be done on the error estimates of source
parameters.
Countrates are estimated assuming that the source shape is a gaussian.
Unresolved sources have the shape of the PSF. This means that
for point-like source we can in future calibrate the true countrates versus
the wavelet countrates, for small wavelet scales. However, this involves
a lot of calibration work and/or numerical simulations.
