Fig. 1: FIMS/SPEAR all-sky data.
From: A nearby dark molecular cloud in the Local Bubble revealed via H2 fluorescence
Top: FIMS/SPEAR FUV H2 fluorescence emission map13. Bottom: map of the ratio of H2 intensity to total FUV intensity. In both the top and bottom panels, the location of the Eos cloud is outlined and appears as a bright fluorescent feature that is not present in the FUV continuum. We determine the on-sky boundary for the Eos cloud on the basis of the magenta contours in the bottom panel, which outline the 10% ratio of H2 intensity.
