8. To examine and edit the parameters of the resultant pointing model, left-click on the SiTechExe GUI "PointXP" button to open the PointXP window. Note that this does not update while the script is running, so you'll need to close and reopen the window to register new points. A typical pointing model for Lesedi has RMS≤2", Peak≤7". Points can be deleted by clicking on them in the display (deleted points turn red) or toggling "true" and "false" on the "CalPoints" tab, where you can also sort the list of points by e.g. error to match the points on the plot. Phi corresponds to azimuth, theta to altitude. The sensitivity parameter should be low, certainly <300.
9. Save the model by clicking "Save Text Calibration File" on the Main PXP tab of the PointXP6 window. The naming convention is YYYYMMDD_SHOC_Right_NorthUp_150points.PXP. If you intend to use the model, also save it as AutoLoadRight.PXP (overwrite existing file) so that it is loaded automatically when selecting the SHOC port. The model file selected for each port is set on the Tertiary Mirror tab of the SiTech TCP Focuser GUI (currently /usr/share/SiTech/SiTechExe/AutoLoadRight.PXP- if you change this, remember to click "SAVE Settings" on the Configuration tab).
