Left: grayscale of the 8 μm GLIMPSE image of GMF 41.0-41.3. The white contour shows the ¹³CO integrated intensity of 1 K km s^-1. The solid black line shows the location of the Galactic midplane at the distance of this filament. The solid black line is the location of the Galactic plane at the distance of this filament. The supernova remnant 3C 397 is the (unrelated) bright IR emission region. Right: color scale of the centroid velocity field from the GRS ¹³CO data where the integrated intensity is above 1 K km s^-1 in the indicated velocity range, shown in the color bar in km s^-1. The blue contour is ATLASGAL 870 μm emission of 250 mJy beam^-1. In magenta circles, we show all v_lsr measurements of BGPS clumps that have velocities within the ¹³CO velocity range and with × those v_lsr values outside of the ¹³CO velocity range. The diamonds are positions in the Wienen et al. (2012) catalog with a matching velocity. The black contours are the ¹³CO integrated intensity of 2 and 7 K km s^-1.
