 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 ​-i' ​to 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.
