Optical polarisation vectors (lines with filled white circles) are over-plotted on a 2° × 2° IRAS 100 μm image of L1521F. The polarisation vectors corresponding to the stars obtained from the Heiles (2000) catalogue selected from a circular region of radius 1° around L1521F are also plotted (lines without circles). Position of L1521F-IRS is shown with a star. The outflow direction is shown as a thick line with two headed arrow. The broken line shows the Galactic plane orientation at the latitude of the cloud. The vector with 2% polarisation is shown for reference.
