Hi, I solved this with my code:

poly_coefs = poly_fit(xvector, yvector, 3,/double,status=estatus)
if estatus eq 2 then begin
xvector=[0,xvector]
yvector=annularSum[xvector]
poly_coefs = poly_fit(xvector, yvector, 3,/double,status=estatus)
print, 'estatusss',estatus
endif

Also, you can add more cases with a case 1: ....

Best regards.
