Description: Allows the magnitude and error of a set of observations to be modified via a VeLa function with this signature: do(mag:ℝ err:ℝ):list, where the list contains the modified magnitude and error. This action can be undone and re-applied via the Edit menu. Here is an example of a do function (slightly contrived: multiplying the magnitude by 10):
do(mag:ℝ err:ℝ):list {
[ mag*10 err]
}
The transformer is accessed via the VeLa Observation Transformer item in the Tools menu:
The Run button can be used to test the function, e.g. by first entering do(5.3 2) after the function. The OK button applies the function to the series selected before the dialog box above opens.
