This HELP field is defined by SPIRE coverage of the XMM-Newton, also known as the High Throughput X-ray Spectroscopy Mission and the X-ray Multi-Mirror Mission Large Survey (XMM-LSS) field.
Click here to get a simple VOX query to get you started. To query the flux columns use f_best_g, ferr_best_g, m_best_g, and merr_best_g for the lowest error flux, flux error, AB magnitude, and magnitude error measurement available. All the main broadband optical and near infrared fluxes are available by replacing g with u, g, r, i, z, y, j, h, k, or ks. A full description of all columns is available here. You can also query the full table with all specific bands available.
