Determining astrometry of V773 Tau A, B, and C. The left hand panel shows the rotation-subtracted image of the V773 system, which was constructed by rotating the image by 180 degrees around the centroid of A (indicated by the red dot) and then subtracting it from the original image. The positive flux image of C is seen to the lower left and the negative flux image of C to the upper right. The positive flux image of the B component is then seen to the upper right of the centroid of A, indicating its location. The right hand panel shows the subtraction of the positive image of C from the location of B, with B marked with a red circle. Residuals from the subtraction processes can be seen around the location of A and B.
