Warning!
The accuracy of this method is variable, according to the geographical position: less than 2 TECu at high and middle latitudes, up to 10 TECu close to the equatorial anomaly (in some exceptional cases). Negative slant TEC values (which are physically impossible) are often observed when they can be low and so comparable to the error in arc offset estimation. They are not discarded because those of them amounting to few TECu can be considered useful as inside the accuracy of the method.
