Examples of schemes used to scan the coma of 67P with Rosetta/MIRO. Each circle has the projected size of the MIRO beam width (7.5′) at the distance of the comet and is projected at the pointed position at the center of the 30 s integration. The scales of the X- and Y -axes are the distance from comet center. Arrows show the scanning direction and its motion during 30 s. The color provides the HO integrated line intensity according to the scale given on the right. The Sun-projected direction is indicated. Blanks along the sampling correspond to data gaps during calibration (once every 30 min).
