A list of data sources for this curve.

Elements must be in either of the following forms:

<id of X column> "(X)," <id of Y column> "(Y)" [ "," <id of error column> ("(xErr)" | "(yErr)") ]
<id of Xstart column> "(X)," <id of Ystart column>"(Y)," <id of Xend column> "(X)," <id of Yend column> "(Y)"
(denoting start and end coordinates for the #VectXYXY style)
<id of Xstart column> "(X)," <id of Ystart column> "(Y)," <id of angle column> "(A)," <id of magnitude column> "(M)"
(denoting start coordinates, angle in radians and length for the #VectXYAM style)

Column ids are of the form '<name of table> "_" <name of column>'.
