This exercise will require the PC to create a MSA program in APT.

Steps:

Go to /user/bethp/jwst. Copy the file msa.txt into your JWST working directory.
Check out one of your test IDs.
Create a New JWST Program in APT. Fill in all of the required information in the proposal information section.
In the Observations section, select New Observation Folder.
In the new observation folder, click on MSA Planning Tool.
In the catalogs section, select Import Catalog. You should import the file that you copied. You can call it whatever you want.
Click on that file once it has been loaded. For the pre-image availability, select not required.
Next, click on New Candidate Set. In the pop-up box, select Add Filter. Select New Weight Filter and use the values of 150 for Minimum and 155 for Maximum.
You can change the name to whatever you want or leave it as New Candidate Set. Click on Make Candidate Set.
Next, select Planner from the middle of the window. It will have a red X next to it.
Put in an orient of 45. For Primary Candidate List, select your new cadidate set. For the Filler Candidate List, select the original list that you imported.
In the dither setup, check Nod in slitlet. Click Add in the Pattern section, and add dispersion=5 and cross-dispersion=5.
In the Exposure Setup, click on Add in the Gratings/Filters. Put in what you want.
In the parameters section, put in your plan name and click on Generate Plan.
At this point, it is best to save your program.
You will be in the Plans section.
You can try click on Show or Send in the pointings section. However, sometimes, this causes APT to hang.
At the top of the Plans section, click on create observation. This will create an observation. You will have a warning about reference stars. You can ignore it because it is a warning. Another option is to create fake reference targets. To do this, you need to go to the targets section in APT and select New JWST Reference Star.
Run observation in the visit planner.
Save your program and check it in. This should be done in JWST SOGS, not PPSIT.
Once the program successfully checks in, run visit update.
Load the program into Spike.
Now that you have the basic steps, you can play around with selecting different parameters and creating new MSA observations.
The NIRSpec team does have a MSA Planning Tool page. Note that the User Guide for MPT is out of date. In particular, steps 3 and 4 are no longer correct. The MSA planning tool is still a work in progress.
