Observations of V644 Sco in the R-band. Top left to right: total intensity, total intensity with template star subtracted, polarised intensity, and the lower limit of the polarisation degree derived using the measured total intensity (without psf subtraction). The images are smoothed by a Gaussian kernel with a FWHM of two pixels. The colour scale is given in counts/s. The bottom row shows the corresponding radial profiles. The total intensity radial profile shows V644 Sco (solid line) and the scaled template star (dashed line). The radial profile of the polarisation degree shows the polarisation degree using the measured total intensity only (solid line).
