Results from applying the Aschwanden et al. DEM model for a particular time during the June 7, 2011 OCBF event. (A) Average coronal temperature. (B) Average density. Here, we have used a varying column depth based on the method of Zucca et al. (2014) and the average temperature map. The density has been saturated at a lower value in order to bring out the lower coronal densities. (C) A plot of the logarithm of base difference of the average temperature. (D) A base ratio plot for the average density, formed by dividing the density values at the current time step by the density values prior to the event.
