Description:
Observed properties of sources in the region S233IR in a field of
3.1 arcmin by 3.1 arcmin, which contains two young stellar
clusters located to the northeast (NE) and southwest (SW) of the field
center (RA = 05 35 49.79, DE = +35 44 01.9). Source positions,
JHK photometry, extinction and estimated stellar mass are provided.
