  We present results on the basis of Dark Energy Camera Legacy Survey (DECaLS)
DR8 astrometric and photometric data sets of the Milky Way globular cluster Pal
13. Because of its relative small size and mass, there has not been yet a
general consensus about the existence of extra-tidal structures around it.
While some previous results claim for the absence of such features, others have
shown that the cluster is under the effects of tidal stripping. From DECaLS g,r
magnitudes of stars placed along the cluster Main Sequence in the
colour-magnitude diagram --previously corrected by interstellar reddening--, we
built the cluster stellar density map. The resulting density map shows nearly
smooth contours around Pal 13 out to 1.6 times the most recent estimate of its
Jacobi radius, derived by taking into account its variation along its orbital
motion. This outcome favours the presence of stars escaping the cluster, a
phenomenon frequently seen in globular clusters that have crossed the Milky Way
disc a comparable large number of times. Particularly, the orbital high
eccentricity and large inclination angle of this accreted globular cluster
could have been responsible for the relatively large amount of cluster mass
lost.
