   * Remedy also produces the rotation angle. To compare that with the plate-solved ACQ camera images, check the FITS header keyword {{{CROTA2}}}. The difference between the Remedy-produced VIRUS rotation angle and the ACQ camera rotation angle is the "acam" angle in shuffle.cfg (I think.)

   * Ultimately, you can test this by running shuffle to observe a star with LRS2-B and making sure it lands in the IFU. Iterating/adjusting may be necessary.
 
+  * It would be best to run 2 or 3 V+ACQ fields and average together the results. VCl* fields are ideal but any of the 14th magnitude star setups should work really.

 === Measure HPF ACAM center/side CFBs positions on the ACQ camera === #hpf_cfb_acq
   * Select one of the red stars from the ENGYY-T-000 program ({{{r*}}} targets)
-  * For the side CFB, run {{{target_setup}}} with {{{-ifu 610}}}
-     * For the center CFB, use {{{-ifu 600}}} as usual
-  * Ask the TO to center and guide on the star on the HPFACAM (side CFB) using the coordinates of the center determined earlier. Note: guiding may not be possible at this position and may require activating a guider and making small offsets to manually center the star on the side CFB.
+     * For the center CFB, run {{{target_setup}}} with {{{-ifu 600}}} (usual hpfacam setup)
+     * For the side CFB, run {{{target_setup}}} with {{{-ifu 610}}}
+  * Ask the TO to center and guide on the star on the CFB (center or side) using the new coordinates determined earlier. Note: guiding may not be possible at the side CFB position and may require activating a guider and making small offsets to manually center the star on the side CFB.
      * For the center CFB this is like a normal HPFACAM setup
   * Store images on the HPFACAM and all cameras throughout this test.
-  * Activate a WFS and allow focus/guiding to stabilize for ∼1 minute, BEFORE asking the TO to handshake to a guider.
+  * Activate a WFS and allow focus/guiding to stabilize for ∼60s, BEFORE asking the TO to handshake to a guider.
   * Ask the TO to handshake to a guider and to monitor the star on the side-CFB of the HPFACAM to verify that it stays precisely at the correct location.
   * Verify that all probes are storing images.
-  * Repeat the following procedure four times in total:
-      * Deploy the ACQ camera mirror (i` filter), wait 10 seconds to stabilize
-      * Store five ACQ images with short exposures so the target star is not saturated, noting the time stamps (please set ACQ cycle time to ≤1s to speed this up!)
-      * Retract the ACQ camera mirror
-  * Do this for both the side CFB and center CFB, noting timestamps
-      * calculate the fplane values for IFU=600 and IFU=610

+  * Store 5 ACQ images with short exposures so the target star is not saturated, noting the time stamps (please set ACQ cycle time to ≤1s to speed this up!)
+     * stack the images (or use the average from individual images) to measure the X,Y coordinates on the ACQ camera of the star.
+  * Retract the ACQ camera mirror
+  * Do this for both the center CFB and side CFB; note that it may be faster to do a trajectory offset from the cCFB to the sCFB, or you can send them as separate targets
+
+  * Repeat this for at least 2 or 3 red stars and average the values.
+
+  * now you should have an ACQ camera X,Y coordinate for cCFB and ACQ X,Y for sCFB
