Areas covered by observations in the Vilnius photometric system. The whole 2° × 2° area wasobserved with the Maksutov telescope of the Molėtai Observatory, and the seven 12′ × 12′ areas were observed with the VATT telescope. Six of them form a black irregular rectangle and the seventh is a separate black square. Two heavily reddened red giants, discussed in Section 4, are plotted as the white dots. The cross designates the position of the dust peak, according to Pagani et al. (2005). The background is a map of the thermal dust emission at 857 GHz (350 μm) measured by the Planck space mission and taken from the SkyView virtual observatory.
