And I was wondering if I could have a two or more modeling, so if the night is very hot I load modeling 1 and ifYes, you can load data points from any ".PNT" file. Although APCC does account for refraction changes due to temperature, pressure, and humidity, there are additional factors affected by temperature, such as the flexure of the various components. The flexure of most materials will change relative to temperature, becoming more flexible as temperature rises.
So, you can either create or use a different model, or live with shorter exposure durations with a model built at a significantly different temperature. In the long term APPM may eventually use multiple PNT file collected over many months to create a dynamic model that accounts for flexure changes due to temperature.
