TOI-561 Stage 30 error

[mar-palt]

Hi Sebastian,

When I try running Stage 30 with TOI-561 data, I get the following error for both the white and spectroscopic light curve fits:

These are my pcf and fit_par files:
fit_par.txt
obs_par.pcf.txt

Hi mar-palt,
I got the same error message and found a solution which at least works for my dataset. My data has just one visit so there is no reason to not tie any of the parameters in the fit_par.txt file. Once I removed all the duplicated lines in the file and tied the parameters, the error in stage 30 was resolved. Maybe this could work for your dataset too.

Hi @mar-palt , just double checking, do you have one or two visits?

[mar-palt]

Hi both,

Sorry for the late response! I have only one visit, and I tried incorporating @n-bachmann's solution and it seems to work, the error isn't present any more. Thank you for you help!

Hi @mar-palt ,

Great that it's fixed!
Just for clarification: If you only have one visit, all values in the "tied" column in fit_par.txt should be "-1" and the lines shouldn't be repeated. Only if you have several visits and you don't want to have the same value across visits (= you dont want to have them tied across visits), then you would repeat the line.
So for example, let's assume you have three visits. Then you will want to have a different normalization for each visit. In the fit_par.txt it will look something like this:

c False 0 8.37 True 6.0 True 8.9 U 6.7 7.0 0.001
c False 1 8.37 True 6.0 True 8.9 U 6.7 7.0 0.001
c False 2 8.37 True 6.0 True 8.9 U 6.7 7.0 0.001

This will give you one "c" value for each visit.
Hope that clarifies it a bit!

This is fixed.
