pblum_mode with absolute mode

[kittipongwangnok]

After I got some parameters when I had a model with pblum_mode of dataset-scaled mode, I switched back to absolute, whereby the luminosity of the system was fully determined by the intensity of the stellar surfaces and the distance. However, the synthetic light curve does not match the observed data. How can I handle this? Do you have some ideas/suggestions? Thank you for your kind assistance.

pblum_mode = 'dataset-scaled' effectively allows you to ignore passband-luminosity-scaling while modifying other parameters, but does not set those parameters to anything when you change to another mode. In the case of pblum_mode = 'absolute', you'll need to set or fit the distance and third light, appropriately, while stellar parameters affect the luminosity, as you mentioned.

The following tutorials might be helpful:

• pblum modes
• third light
• 2023 workshop tutorial on flux-scaling
