Hi Joris,
I want to fit a binary of which one component is a BB that may result from accretion disk. Here, when I use a BB to fit my source, I find that the WISE W3 and W4 band also have a very bad fit. Therefore, I want to add to a BB within the model so that
see if it can fit well.
In addition, If I consider a BB from the accretion disk, should I use the first case and does a the atmosphere model of star still apply?
Fitting results of the main sequence star model as follow:
Thanks!

Hi Joris,
Thank you for your reply.
Here, I should how to set up to add BB model into the speedyfit (add BB model to **.yaml?). Could you give my a model of 2 components?
This source has a V band magnitude of approximately 13.7, it may be too bright for sdss?
Thanks!

Hi Joris,
Here, I try to use the grid binary model, but the model of blackbody seems too hot for an accretion disc. Here, Is the speedyfit have able to set up a cold temperature blackbody (e.g 2000-4000 K)?
If I'm not mistaken, it only be set up like this:

Hi Joris,
I try to adjust the limits ([500, 3000]), but the speedyfit throw an error. Could you tell me the reason for this error?
The error is as follow:

Hi Joris,
This is setup file!

Hi Joris,
Here, I try to use the get_table_single of speedyfit.model to combine 'kurucz' and 'blackbody', but I discovery that the shapes of the array is not consistent. Therefore, I guess the former error may be same this reason?

Hi Joris,
Thank you for your help!
Here,I have the ability to fit the SED combining kurucz atmosphere and blackbody. The result of combining kurucz atmosphere and blackbody model fit well compared to the kurucz atmosphere. Do you think it is more reasonable to add BB's model for fitting?
In addition, I don't understand what the symbol of the cross (×) on the graph represents and what the C of O-C refers to the calculation result from?
Thanks!

Hi,
Thank you for your reply again.
If the crosses is the modelled fluxes, then the WISE W3 is lower compare with the modelled fluxes. Why is W3 so low, what may be the reason for this, do you have any suggestions for this?
Thanks!

No problem. Glad I could help.
