Performing a CSD

Open Charge State Distribution Scan

Select source (selection popup may default to the upper left screen)

Adjust range and gap if desired

Click Scan start

Do not close the application until the scan is complete

When done, click Save the scan and save in the default folder

Use the cursor to get the position of each oxygen peak on the CSD

Fill in the measured positions in the M/q measured column

Click Calc to find the correction

Click Apply to use it

Correction info is vague and needs expanding on, this would heavily improve with a “why” page, but that's a different issue
