# Generate the lists of products
pos <- sf::st_sfc(sf::st_point(c(-57.8815,-51.6954)), crs = 4326)
time_window <- as.Date(c("2018-02-21", "2018-03-20"))
list_safe <- s2_list(spatial_extent = pos, time_interval = time_window)

# archives already available online and 2 stored in the Long Term Archive)
