IRIS Data Products -- Almost

I was about to release my first set of IRIS data products and realized that I need to add a bit more data to the final product, AND most importantly I need to write up a document describing how I created the product.

I'm very excited about getting this data out, but it'll take a little more time to get it out.  The cool thing about being an independent researcher is that I can make my own timeline.  This way I can be satisfied with what I do rather than trying to finish on a schedule with only decent results.

Anyhow, here's a sample of the current data product:

The first column is the y-pixel location.  2nd column is the distance, in arc seconds, from the center of the sun along the y-axis of the image raster.  The next two columns is a pair: the first value (column 3) is the wavelength of the peak value of the MgII k 2v line, and the second value (column 4) is the intensity of that peak.  Columns 5 and 6, and 7 and 8 are the same, except they are for the MgII k 3 and MgII k 2r spectral features.

I need to add the distance from the center of the sun along the x-axis, and I need to add the UTC of the observation.  At the moment I'm only doing this for "sit-and-stare" data which means that the slit isn't scanning the image raster but is stationary.  I still need to work out how the scanning works as far as the data goes.  That'll come in a later version of the data product.

Here's a picture and a plot of the data that I'm working with:

IRIS is a NASA small explorer mission developed and operated by LMSAL with mission operations executed at NASA Ames Research center and major contributions to downlink communications funded by the Norwegian Space Center (NSC, Norway) through an ESA PRODEX contract.
