Frustration is setting in.

I didn't do all I had planned for today. I am hanging my head down in remorse. I did about half. I *almost* analyzed 2 of the 4 big files. I found that the other 2 need some re-reduction - the edges of the slits are too bright for some reason and that screws up the following extraction which thinks the light is in the artificially bright edge. I need the re-run the the extraction with a lower "upper" parameter to get rid of the edge.

My computer keeps extracting sky spectra.

A friend of mine is visiting town this week and he is staying on our couch tonight. We had a BBQ in his honor so that he can meet some people and so that I can have people over at our house which I love. Lots of people came. We had a good time.

Tomorrow: get up early and have a short hike. Re-extract the 2 files which I found to be screwed. Re-run the cross correlation for them. Keep extracting sky spectra. Write the n-th nearest neighbor algorithm.
