	FirstLine   string
	SecondLine  string
	DataLine    string
	Epoch       float64 // epoch of this dataset
	Header      int     // lenght of header in lines
	CurrentLine int64   // current line from dataset, header lines are NOT counted
	PeekData    []byte  // peek into file to get the type
}

type AstrodataFile

type AstrodataFile struct {
	Datafile    string
	Fd          *os.File
	Rd          *bufio.Reader
	Compression int // value from COMP_*
