Unclear how exactly we did this. Assume constant y and refit for height at all positions?
To look at the jets in these selected stars we used a subtraction and eliminated the brighter emission of the stars themselves. For each wavelength we subtract the Gaussian fit from the stars' profile, which leaves behind a background and any unusual emission. In these left over images should be able to see jets, if there are any, and to examine more closely the profiles and intensities of the jets. Since we are only interested in looking at the vicinity of the oxygen lines, we selected a region around these lines and performed the subtraction. The images are shown in Fig.(ref).
