HMI continuum intensity image (left), magnetogram (middle) and classification image (right) from May 30, 2011. The classification image indicates the positions of the pixels classed as network and faculae (white), and sunspots and pores (black). The latter includes magnetic signal adjoined to sunspots and pores, counted to them to avoid counting their magnetic canopy, possible bright structures within penumbrae and straylight as network and faculae erroneously. The continuum intensity image and magnetogram are scaled between 0.6 and 1.2, and −80G and 80G respectively as in Fig. 4
