passbands in Phoebe correspond to the V- and I-band light curves (LCs) of OGLE

I'd like to ask which two passbands in Phoebe correspond to the V- and I-band light curves (LCs) of OGLE. Thank you very much!

In OGLE (I'm a member of the team) we always calibrate the light curves to the standard photometric system before publishing. That means the passbands correspond directly to Johnson V and Cousins I. So in Phoebe you can safely use those two filters for OGLE LCs.

Thank you very much. I have another question: If there is no filter and white light is used for observation, how should the Phoebe filter be set?

[mwrona77]

In that case, I would recommend setting the passband in Phoebe to “Bolometric: 900–40000”.

Thank you very much!

I'm not sure that using bolometric will have the desired effect. Bolometric is meant only for irradiation effects between the two stars where there actually is no filter. On the flip side, there is no detector that would have a flat response between 90nm and 4um, so that "white passband" is waaaaay too broad. I think TESS or Kepler passbands are close to "white" but, ultimately, it will depend on the response curve of the optics + CCD.

Thank you very much for your help. Welcome to Kunming again.
