Use this option only together with mc_panorama_view.


mc_panorama distr_photons_over_pixel

 
With only mc_panorama_view all photons for the same pixel are emitted into exactly the same direction. The finite solid angle that is covered by one pixel is not accounted for. With mc_panorama distr_photons_over_pixel the photons are distributed over the FOV covered by the pixel.


mc_panorama no_pixel

 
Useful for calculation of radiance distributions which shall be exactly charted. Originally mc_panorama_view was meant to calculate images like produced by a CCD camera. You set the edges of your desired image and the resolution of the sensor. MYSTIC will then calculate the radiances at the center of each pixel. This implies that values for the edges of the image as given by the input file are never computed. The border angles for which radiances are computed are shifted half a pixel to the inside of the domain. With mc_panorama no_pixel the edging values as given in the input file are directly hit. A short example: Assume you only have three pixels. You choose your edges to be at \phi=0 and \phi=180. With mc_panorama no_pixel MYSTIC will calculate radiances at \phi=0, \phi=90 and \phi=180. Without this option you will get values for \phi=30, \phi=90 and \phi=150.


mc_panorama quicklook

 
This option allows to do a fast calculation in order to see whether you have set your parameters right. All panorama pixels are run in a fast mode: only one photon is started per pixel, it is moved till to a fixed optical depth (0.1), and then a local estimate is performed. In case the local estimate is done scattering (i.e. the photon has not hit a surface before reaching tau=0.1), isotropic scattering is assumed. Then the photon is killed. We suggest you turn off Rayleigh scattering and aerosols while using this option. The result lets you see roughly where your panorama is looking at surface, sunlit clouds, shaded clouds, or slanted clouds.


mc_panorama with_direct_rad

 
Output is direct plus diffuse radiance. Use together with mc_panorama distr_photons_over_pixel.
