There are some changes in the international releasing of DR5 comparing with the internal version. The reason for these changes is that we update the method of calculating the ratio of signal to noise for r band (SNR). For the international version, the values of SNR are set to -9999 when the number of pixels available for calculating SNR is less than half of the total number of pixels in r band (pixels whose the values of inverse variance are equal to 0 are not available for calculating SNR). As a result, there are , which are listed as follows:

(1) The values of SNR have been changed for 42,468 spectra, and the detailed information are provided in list.

(2) 1,275 spectra have been abandoned from the international version after recalculating the SNR, because there spectra do not satisfy the release criteria of SNR. The detailed information are provided in list.

(3) 6 spectra have been added into the international version after recalculating the SNR. The detailed information are provided in list.
