If you find temp/time data for the publically displayed points, in order to make sense of the data at any point, e.g., a,b,c,d, you need to know exactly where that sensor is and to what that sensor is attached to on the vehicle. As the vehicle moves things around and opens things up, that data point temperature can change dramatically even while being realatively at the same solar distance. The temp will depend on it's position relative to the sun as well as it's distance from the sun, the view factor to the sun, the thermal mass associated with the area to which it is mounted, and thermal conductance to attached structures. A sensor on the thin sheet of the sunshield facing the sun will show a temp based primarily on orientation and distance to the sun. A sensor on a beam will take time to equilibrate due to combinations of radiant input and thermal conductance to attached structure areas. A temp on the backside of the sunscreen, radiating to space, will be at a temperate controlled by thermal input from attached structures.
I cannot find a detailed description of where the published sensor temperatures (a,b,c,d) are located and to what they are attached. I was hoping to find out how well the actual temperature are comparing to predicted temperatures for the same points. I did thermal analysis on Apollo (eons ago) and hoped to see how things had improved over the years. Perhaps later data dumps will provide info.
