We report here some errors in Tables 2 and 3 of our paper “PHOTOMETRIC ANALYSIS OF TWO K SPECTRAL TYPE CONTACT BINARY SYSTEMS”, published in RMxAA, Vol. 58, p. 237 (2022). Table 2 refers to the system J135349.

These unfortunate errors have been corrected and the new Table 2 is shown below:

Another error was found in Table 3 for system J150957, for which R₂(R_⊙) and L₂(L_⊙) had to be corrected.

The new Table 3 is shown below.
