| 11 | This tool is to approximately estimate the resolution of Q based on the |
|---|
| 12 | SANS instrumental parameter values assuming that the detector is flat |
|---|
| 13 | and vertical to the incident beam direction. |

| 19 | 1. Change the default values of the instrumental parameters as desired, |
|---|
| 20 | and type the qx and qy value where the resolution |
|---|
| 21 | is calculated. |

|---|
| 31 | the panel. Two dimensional resolution weight distribution |
|---|
| 32 | (2D elliptical Gaussian function) will also be |
|---|
| 33 | displayed in the plot panel even if the Q inputs are outside |
|---|
| 34 | of the detector limit. |
|---|
| 35 | The red lines indicate the limits of the detector. |
