The survey footprint in the HSC-SSP and the expected tidal debris from the different orbital model of the LMC. The left panel shows the case for the first-passage model of L2M10first from E. Vasiliev (2024). The gray dots show the expected tidal debris. The sequential colored dots show the orbit of LMC from the past (yellow) to now (green). The right panel shows the case for the second-passage model of L2M10 from E. Vasiliev (2024). The gray dots and the sequential color are the same as in the left panel. For both panels, the north, spring, and fall fields in the Subaru HSC-SSP survey are drawn as the cyan, pink, orange areas, respectively. This figure indicates that the hints for the past orbit of the LMC can be seen as the substructure toward the north field.
