Data Reduction Frequently Asked Questions

How can I improve the sky correction of my STARE data?

Depending on the observations in case of crowded field, you may have to define yourself the windows in the slit where there are sky positions. This can be achieved by using the parameters sky-positionN and sky-hheightN. Alternatively you can increase the power of the spline used for the sky corrections by changing the values of BSPLINE parameters.
