TurbuLenZ input file tB.inp Simulate two layers (2000m, 10000m) at 500 nm for a single 8.4 m telescope Running this file takes about 40 minutes on a PowerMac G4/450 MHz with IDL 5.4 and 256 MB RAM. 2 number of turbulent layers 1 number of telescopes/apertures 1 number of stars/viewing directions 20 number of time steps 40 pixelscale in the aperture plane (pixels per meter) this number should be at least twice the smallest 1m/r0[m] value 0.0000005 wavelength (meters) 2500.0 height difference (meters) above which fresnel diffraction is used for light propagation storage flags: 1 1: save total phase screens; 0: don't 7 bit 0 = 1: save centroids and intensities (remove all l0tNSM files) bit 1 = 1: save intensity distribution in the image plane (speckle image) bit 2 = 1: save phase screens and amplitude screens of the telescopes (after propagation through all turbulent layers) 0 same as before, but for each turbulent layer individually 1 number of first filename 2 if 2: initialize phase screen at first time step, use RAM for temporal files if 1: initialize phase screen at first time step, use hard disk for temporal files if 0: use phase screen stored on hard disk for first time step, use hard disk for temporal files turbulent layer(s), high to low altitude 0.00 decorrelation factor 75. outer scale of turbulence (meters) 0.1 windspeed (meters per time step) 45.0 direction of the wind (degrees, counter clockwise, 0 deg: phase screen moves right) 0.1 r0 (meters) 10000.0 height of the layer above the telescope (meters) next layer(s) 0.00 decorrelation factor 75. outer scale of turbulence (meters) 0.05 windspeed (meters per time step) 65.0 direction of the wind (degrees, counter clockwise, 0 deg: phase screen moves right) 0.05 r0 (meters) 2000.0 height of the layer above the telescope (meters) next layer(s) telescope(s) 8.4 aperture (meters), SH sensor 0.01 pixelscale in the image plane (arcsec per pixel) 400 size of the images of the image plane (pixels) 0.0 relative x-position of the telescope (meters) 0.0 relative y-position of the telescope (meters) next telescope(s) relative star(s)/viewing direction(s) (arcseconds) 0.0 0.0 123456789 check
