    batch mode (file upload):

    

        

            Upload a CSV or TXT file with columns:
            logg, feh, cfe
            (header required; order matters if unnamed)
        
        

        
N samples (max 1000): 
        

    
    
        Example format (uncertainties optional, default=0.1):
        
logg,logg_err,feh,feh_err,cfe,cfe_err
1.5,0.20,-3.0,0.10,1.0,0.15
2.0,0.15,-2.5,0.10,0.8,0.20
3.0,0.30,-1.0,0.15,2.0,0.10
    
    
    






    information:



   

     
Based on the procedures described in
Placco et al. 2014c, ApJ, 797, 21 (ADS |
pdf)
     
Parameter space:
       

         
 0.0 ≤ log(g) ≤ 5.0 (0.1 steps)
         
-5.5 ≤ [Fe/H] ≤ 0.0 (0.1 steps)
         
-1.0 ≤ [C/Fe] ≤ 3.0 (0.1 steps)
       
     
Corrections for parameters outside these ranges

will default to the closest point in the grid.
     
Batch mode: upload a CSV/TXT file with a header row.

         A new CSV with a CCOR column will be returned.
