Imageof the inverted dust distribution in a vertical plane containing the Sun (located at 0,0) and oriented along Galactic longitude l = 150°. Coordinates are in parsecs. The quantity represented in black and white is the differential extinction. Iso-contours are shown for 0.0002, 0.00045, 0.001, 0.002, 0.005, 0.01, 0.015, and 0.02 mag per parsec. The paths to the target stars whose longitudes are within 1.3 degrees from the longitude of the represented plane are superimposed. The stars are numbered as in the text and drawn at the bottom of the figure; additionally, the Doppler velocities and approximate columns of absorbing K I in 10¹⁰ cm⁻² units are listed for each target (in parentheses after velocities). Stars’ numbers are indicated in yellow or black. The list of targets is given by decreasing latitude. For distant targets falling outside the image, their numbers are indicated along their paths at the boundary of the figure. The preliminary velocity assignments to the dense clouds are indicated by arrows pointing outward (inward) for positive (negative) radial velocities. The length of the arrow is proportional to the velocity modulus.
