| - | * Cell parameters: cell_a, cell_b, cell_c in Angstrom; cell_alpha, cell_beta, cell_gamma in degrees | + | * **Cell parameters**: cell_a, cell_b, cell_c in Angstrom; cell_alpha, cell_beta, cell_gamma in degrees (typically taken from [[software:maud|Maud]] refinement) |
| - | * Lattice type: P = primitive, F = face-centered, A = A-centered, ... | + | * **Lattice type**: P = primitive, F = face-centered, A = A-centered, ... |
| - | * Distance = sample-detector distance in µm | + | * **Distance** = sample-detector distance in µm (typically taken from [[software:maud|Maud]] refinement) |
| - | * O-matrix (check the [[|concept of the O-matrix]] if you are not sure) | + | * **O-matrix** (check the [[dac_experiments:geometry|concept of the O-matrix]] if you are not sure) |
| - | * Omegasign = rotation direction (1 = clockwise, -1 = counterclockwise) | + | * **Omegasign** = rotation direction (1 = clockwise, -1 = counterclockwise) |
| - | * Tilt (be careful with this one: Tilt in ImageD11 is sometimes not the same as tilt in other software!) | + | * **Tilt**: Be careful with this one: Tilt in ImageD11 is sometimes not the same as tilt in other software! (usually keep 0 and refine later) |
| - | * Wavelength in Angstrom | + | * **Wavelength** in Angstrom |
| - | * y_size, z_size: size of one pixel in y direction and z direction in µm | + | * **y_size**, **z_size**: size of one pixel in y direction and z direction in µm |
| - | * y_center, z_center: pixel coordinates of the beam center (if your detector has 2048x2048 pixels the center is usually somewhere close to 1024x1024) | + | * **y_center**, **z_center**: pixel coordinates of the beam center (usually taken from [[software:dioptas|Dioptas calibration]]: ''y_center = Dioptas Center X'' and ''z_center = 2048 - Dioptas Center Y'') |
| + | * Supplementary parameter **cell_sg**. You can also provide your material space group. This has to be done manually with a text editor and can not be done using the Graphical User Interface. If the space group is provided, ImageD11 will use xfab for generate unique hkls. | ||
