Example of WT planes in two different HEALpix fields corresponding to the Sgr core (top row) and the middle part of the leading arm (bottom) at the three different scales analyzed here (three columns, from left to right for small to large). The color indicates the value of the WT coefficients, where darker blue means higher WT, i.e., higher intensity of the substructure, while red colors are for under-dense regions. Crosses are peaks detected in these WT planes. The peak of the Sgr stream/dwarf is marked in green and appears to be well separated from the general field.
