| | 195 | * Determine the X,Y coordinates of the star's RA,Dec coordinates, just to verify |
| | 196 | * Retract the ACQ camera mirror |
| | 197 | * Tomorrow afternoon, verify that the //Panacea// data reductions show nicely centered stars on the LRS2 exposures - that will be the position of all targets hopefully. |
