  In this paper, we analyzed pulse profiles of Swift J1626.6+5156 using the
lightcurves from RXTE-PCA observations between MJD 53724 (just after the
outburst) and MJD 55113 and a Chandra-ACIS dataset on MJD 54897 with a 20 ks
exposure. We found that pulse profiles show morphological variations and
pulsations do not cease even $\sim 1200$ days after the outburst. Despite these
variations, we did not find any significant variation in the pulsed fraction
with decreasing X-ray flux.
