 Before starting: Before starting:
-  * Target ID 4 is for making pointing models +  * Back up /etc/rts2/ir.model 
-  * Make sure exposure script for current camera is there, with an appropriate exposure time. +  * Make sure the script for target 4 is appropriate, at least two exposures to allow astrometry to complete before the next pointing
-Assuming the telescope is T0 +  * Clear the existing model with 'rts2-opentpl-errors -I <ip> -N <port> --reset-model
-  rts2-mon/T0: **Set** model count to 0+To create the new model:
   - rts2-mon/EXEC:   - rts2-mon/EXEC:
-    - **check** auto_loop and default_auto_loop are true +    * Verify auto_loop and default_auto_loop are true 
-    - **run** 'now 4' (for ~20 exposures) +    * Execute command 'now 4' 
-  - shell: (recommended) +  - shell: 
-    - **run** 'rts2-nightreport -ito look at observations as they happen +    * Track the number of points with 'rts2-opentpl-errors -I <ip> -N <port> --sample
-    **back up** old model /etc/rts2/ir.model +    * After $ENOUGH pointsdo 'rts2-opentpl-errors -c' to calculate (and load) the new model. 
-  - after ~20 exposures**run** 'rts2-opentpl-errors -c' to calculate (and load) the new model. +  - rts2-mon/<tel>: 
-  - rts2-mon/T0: **run** save_model (to write new /etc/rts2/ir.model+    Execute command 'save_model(to write new /etc/rts2/ir.model
  
-Repeat this above pattern again with a larger number of points (e.g. 50) to refine it.+Astelco suggest starting with a 7 point model Martin Jelinek suggests finishing with 50 points.
