Data from communications between satellites and missing Malaysia Airlines Flight 370 was released Tuesday, more than two months after relatives of passengers say they requested that it be made public.
Malaysian authorities publishedÂ a 47-page documentÂ containing hundreds of lines of communication logs between the jetliner and the British company Inmarsat's satellite system.
The information provided isn't the whole picture but is "intended to provide a readable summary of the data communication logs," the notes at the start of the document say.
Some passengers' families, unsatisfied by official explanations of the plane's fate, say they want an independent analysis of the complex information, a process that could take some time.
"The first thing we're going to expect feedback on is does the data look right," said Sarah Bajc, whose partner, Philip Wood, was on the missing jet. "Is it as complete as we're being led to believe it is?"
She said, though, that she was "annoyed" that Inmarsat and Malaysian authorities hadn't released the raw data in its entirety.
"I see no reason for them to have massaged this before giving it to us," she said.
