TL;DR: In this article, the authors presented initial results from time-series imaging at infrared wavelengths of 0.9 deg^2 in the Orion Nebula Cluster (ONC) during Fall 2009 and obtained 81 epochs of Spitzer 3.6 and 4.5 μm data over 40 consecutive days.

TL;DR: In this article, the spectral energy distributions (SEDs) of a subset of YSOs were fitted and properties for those that were well fitted and the total mass of these well-fitted YSOIs was estimated to be approximately 2.1 × 10^6 L. The YSO population is biased toward intermediate-to high-mass and young evolutionary stages.
