MXDF Moffat fit of the M star RID-5102. The fit is performed on 20 narrowband images of 232 Å width, equally distributed along the MXDF cube wavelength axis. Examples of the first, central, and last images (each box side is 5 arcsec in length) are displayed in the first column. The corresponding Moffat fit and residuals are shown in the two other columns. The FWHM and β Moffat fitted values are shown in the upper and bottom right panels, together with their polynomial approximation.
