Why the EOD OHLC chart data different than 1 min chart data?

Why the EOD OHLC data different than 1 hr ,5 min or 1 min data ? Here is an example today 15/12/2017 Cipla’s OPEN is 597 as per BSE and NSE on EOD chart but on 1hr to 1min charts Cipla’s OPEN is 596 for NSE and 599.75 for BSE.

They must be calculating the EOD data by some mean what is that? any idea
