Malaysia's government and British satellite firm Inmarsat on Tuesday released the data used to determine the path of missing Malaysia Airlines flight MH370, responding to mounting calls from passengers' relatives for greater transparency.

The data from satellite communications with the plane, which runs to 47 pages in a report prepared by Inmarsat, features hourly "handshakes" - or network log-on confirmations - after the aircraft disappeared from civilian radar screens on March 8.

Families of passengers are hoping that opening up the data to analysis by a wider range of experts can help verify the plane's last location, nearly three months after the Boeing 777 with 239 passengers and crew disappeared.

The data's release had become a rallying cry for many of the families, who have accused the Malaysian government of holding back information.

"When we first asked for the data it was more than two months ago. I never dreamed it would be such an obstacle to overcome," Sarah Bajc, the American partner of a passenger, told Reuters from Beijing.

Based on Inmarsat's and other investigators' analysis of the data, the aircraft is believed to have gone down in the Indian Ocean, off western Australia.

Malaysian investigators suspect someone shut off MH370's data links making the plane impossible to track, but investigators have so far turned up nothing suspicious about the crew or passengers.

In the hours after the aircraft disappeared, an Inmarsat satellite picked up a handful of handshake "pings", indicating the plane continued flying for hours after leaving radar and helping narrow the search to an area of the Indian Ocean.

The dense technical data released on Tuesday details satellite communications from before MH370's take-off on a Saturday morning at 12:41 a.m. local time (1641 GMT) to a final, "partial handshake" transmitted by the plane at 8:19 a.m. (0019 GMT). The data includes a final transmission from the plane 8 seconds later, after which there was no further response.

The data also featured two "telephony calls" initiated from the ground at 1839 GMT and 2313 GMT that went unanswered by the plane.

Malaysian officials were not immediately available to answer questions on the data.

Bajc said experts on flight tracking who have been advising the families would now be able to analyse the data to see if the search area could be refined and determine if Inmarsat and other officials had missed anything.

But she complained the report released on
