Generate a list of Footprints of sky objects Sky objects don't overlap with other objects. This is determined through the provided `mask` (in which objects are typically flagged as `DETECTED`). The algorithm for determining sky objects is random trial and error: we try up to `nTrialSkySources` random positions to find `nSources` sky objects. Parameters ---------- mask : `lsst.afw.image.Mask` Input mask plane, which identifies pixels to avoid for the sky objects. seed : `int` Random number generator seed. config : `SkyObjectsConfig` Configuration for finding sky objects. Returns ------- skyFootprints : `list` of `lsst.afw.detection.Footprint` Footprints of sky objects. Each will have a peak at the center of the sky object.
