ρ Ophiuchi intensity SED. QUIJOTE-MFI data points are depicted in red together with other ancillary data (blue), including WMAP 9-yr (green), Planck (orange), and COBE-DIRBE data (light green). At intermediate frequencies, the excess emission associated with the AME clearly shows up. A joint fit has been performed consisting of the following components: free-free (orange line), AME log-normal model (purple line), CMB (blue line), and thermal dust (green-olive line). The black line represents the sum of all components.
