RHESSI rotating modulation collimators generate Fourier components (real and imaginary parts) in a series of circles in the uv-plane. Making images with uv_smooth consists of
- interpolating the visibilities in the uv-plane,
- reconstructing the image of the source by means of a Fast Fourier Transform inversion, and
- reducing the ringing effects by imposing a positivity constraint.
Using the UV_SMOOTH algorithm at the command line:
| Select algorithm | o->set, image_algorithm='uv_smooth' | or 'uv' or 'uvs' or 'hsi_uv_smooth' |
|---|
| Object Class | HSI_UV_SMOOTH |
|
|---|
| Extract Object | uv_obj = o->get(/obj,class='hsi_uv_smooth') | Extract the object used in the hsi_image object, o |
|---|
| Parameter Prefix | uv, e.g.
uv_show_vismap = o->get(/uv_show_vismap)
uv_control = o->get(/uv, /control)
uv_info = o-> get(/uv, /info)
uv_all = o->get(/uv) | All parameter names specific to this algorithm have this prefix |

| Parameter Table | UV_SMOOTH Object Parameter Table | List and short description of control and info parameters specific to this algorithm |
