ionic 3 passing data to popover

I am unable to make it work. The popup calling code is

presentPopover(myEvent){
        //alert('invoke popup')
      let popover = this.popoverCtrl.create(PopoverPage, this.data);
      popover.present(
          {
            ev: myEvent
          }
      );
}

and the part where i need to access currently is:

export class PopoverPage{

  constructor(public viewCtrl: ViewController) {
   // alert('in the popup')  
   //alert(this.data)
  }

So how will the data be avaialbe in the popupover page component ?
