NuSTAR_1shell InstrumentA model of the NuSTAR-telescope using just a single shell as optical element. That means to make use of this instrument it is necessary to run a series of simulation while varying the input parameter shellnumber. The model needs as input two geometry files (parabolic_datafile and hyperbolic_datafile), which contains (in ascii) tabled details about the geometry of the shells. The data in the geomfile is assumed to be in the format: #row L/m rad_h/m rad_m/m rad_p/m ... row: running index for the rows/rings L: The length of the plates for this ring rad_h: The radius at the "hyperbolic" end of the optic. At the detector end. rad_m: The radius at the midpoint of the optic. This is the reference. rad_p: The radius at the "parabolic" and of the optic. At the source end. Example: NuSTAR_1shell.instr shellnumber=1
| Name | Unit | Description | Default |
| FL | m | The focal length of the optical system | 10.12 |
| FLd | m | The distance from the optics centre to the detector. If 0 the detector is placed at the focal plane. | 0 |
| optics_dist | m | The distance between souce and optic. In space this would be quite large :-). | 10 |
| offaxis_angle | arcmin | Angle of collimated light from source | 0 |
| drx | 0 | ||
| dry | 0 | ||
| drz | 0 | ||
| reflectivity | Data file containing reflectivities (such as from IMD) | "mirror_coating_unity.txt" | |
| E0 | keV | Central energy of X-rays | 5 |
| dE | keV | Half spread of energy spectrum to be emitted from source | 0.001 |
| shellnumber | The row number for the miror module. This defines the shell. | 0 | |
| parabolic_datafile | File which contains the geometry of the parabolic (primary) mirrors. (i.e. radii,lengths) | "om_con_1a_110901_t1.txt" | |
| hyperbolic_datafile | File which contains the geometry of the hyperbolic (secondary) mirrors. (i.e. radii,lengths) | "om_con_3a_110901_t1.txt" |
