SIMPLIFIED High Speed CWFS Data collection (no DIMM2, no fixed azimuth!)

0. In June 2022 it became temporarily necessary to run this command to de-activate the firewall that is somehow preventing VimbaViewer on Zeus from connecting to the CWFS camera: sudo systemctl stop firewalld

0. consider doing this test as requested by Hanshin, probing a range of observing conditions.
   Note that the primary DIMM must be running and collecting IQ data during this test

1. Several minutes before the end of your science target, select a star from the BSC with magnitude 6-7; run target_setup on the IHMP position (000) as shown below: [stevenj@zeus ~]$ target_setup -cat bsc 2183 W -ifu 000 -to

2. When able, go_next on this target with the usual setup commands.

3. As the telescope is moving into position, ask the TO to power on the CWFS and restart PAS (can do this during go_next). Note that the RA may need to restart their TCS GUI or at least stop and start images again.

4. Ask the TO to setup on the IHMP position, handshake to the guider, and to center and activate a WFS.

5. Make sure all probes are storing images.

6. Ask the TO to retract the ACQ mirror and deploy the CWFS mirror.

7. Offset from IHMP to CWFS with this command:
   syscmd -T 'offset_trajectory(dx_ang=-5.1, dy_ang=-3.9, adjust_probes="true")'

8. Try using a 1-5s exposure time for CWFS, and be sure that the "process" and "store" checkboxes are enabled on the "CWFS control" window in the TCS GUI.

9. Look at CWFS x and y offsets (in the CWFS metrology window) and adjust the offset command (listed above) until offsets are less than 0.3".

10. Once the CWFS is well-centered, run this command to allow VimbaViewer to take control of the CWFS:

syscmd -p 'CWFS_RelinquishControl()'

11. On zeus Start the VimbaViewer by running: VimbaViewer.

12. The first window that starts up is the camera select window. Click the check box next to the CWFS camera (it is the only one not black-ed out since you just relinquished it). Do not exit the Camera Select Window or the Camera Control Window (which pops up when you click the check box) will also exit.

13. Load CWFS camera settings file by clicking the button at the top. Choose the file called /home/mcs/astronomer/cwfs_4x4.xml . This will set the binning and ROI settings correctly.

14. In the "Brightness" tab, set the exposure time between 5,000 and 20,000 micro-seconds (or even shorter if necessary to avoid saturation). If you like, you can verify that the ROI tab shows that the binning is 4x4 and the ROI numbers are OffsetY:0, OffsetX:56, Height:296, Width:296

15. Click "play" icon to see images, then click "stop". To check for saturation, click File --> Save Image As and save the most recent image as tiff somewhere easy like ~/test.tiff. You can open this with ds9 -photo test.tiff to see how it looks. Adjust exposure time if necessary.

16. Set the parameters for a single series of 25,000 (50,000) images by selecting File->Image Series Options... from the File menu. You may have to create the CWFS/ directory in the night's directory.

Format = .tiff

Name = YYYYMMDD_HHmm where YYYYMMDD_HHmm are year, month, day, hours, and minutes), ... for each image series that night

Destination Path = /hetdata/data/ImageQuality/YYYYmmdd/CWFS

Number of Images = 25000 (50000)

17. Start this image series at precisely 0s past the minute, and note the time it starts, to enter in NR later. Taking 25,000 (50,000) images should take 14 (28) minutes, and the speed should be around 40-50 FPS (fast enough).

18. Note the state of the louvers and the frame rate (Frames Per Second, FPS) during this test (to be entered in the NR later)

19. When this set is completed, you can cancel the trajectory and send the next target for the night. To return the CWFS to its normal state, click the "X"s in the top right corner of the Camera Control Window and the Camera Select Window. Then give control of the CWFS back to PAS/PFIP with:

syscmd -p 'CWFS_TakeControl()'

20. Ask the TO to power off the CWFS camera and retract the CWFS mirror.

21. Add night report entry. Use the "Target" option next to the "Add" button at the bottom of the NR. Either add the target from the queue or enter something like this:
    • Target: CWFS test
    • category: engineering
    • program ENG23-2-000
    • instrument CWFS
    • exposure time: 840s (1680s)
    • start, estart, end times

22. Add a comment to the observation in the NR (NOT the activity log) with the image series start time (hh:mm:ss), the Vimbaviewer exposure time (in microseconds), the FPS, and the louver status. For example:

estart=06:01:00, 10,000us exposure, 42.7 FPS, louvers 20% open
NOTE: do not say "20% louvers", instead say whether it is "louvers 20% open" or "louvers 80% closed"
