To Do

Reference Star

Calculate equivalent width of H-alpha line.

Measure slope of continuum (How to do this?)

Line Fluxes

Should calculate line flux for [O I] and H-alpha.

Velocity Plots

Questions

Basic Reduction Having trouble with the flat field images. I have a four observations for 2013 but did not get any flat fields. In the GSA I don't see any that fit my filter/central wavelength set up.

Should be okay to use older flat fields on my new data.


Flux Calibration Have reduced the standard star. Image was centered 600nm with no 605 so there are chip gaps in my final spectrum, will that be a problem?

Need to use it to flux calibrate the already reduced data.

Will not be a problem. I need to change my reduction process to flux calibrate and then extract. gscalibrate does not work on the stacked images (the are not MEFs).

Timeline

Feb 24 - Mar 2:

Finish reduction/calibration pipeline - Reduce standard star data - Flux calibrate and Telluric correct spectra

Finish final draft of comprehensive literature review - Need to discuss with Bernadette

Mar 3 - Mar 9:

Final Reductions -New nights of data -flux calibrate -Telluric correct (Use standard star?)

Study the flared disk method in HYPERION - How does the density equation turn into the code?

Get paper ready for discussion on Mar 11

Mar 10 - Mar 16

Email Bernadette about follow up conversation - Talk about analysis techniques - Send updated Summary/Introduction to project (latex)

Analysis of spectroscopy - Equivalent width measurements of [OI], H-Alpha and [Fe II] - Spectral line fits?

Analysis of photometry - Integrate new data into old data - Any changes? - Migrate all the photometry plots to matplotlib

Reduce any new data

Work on Self-Shadowed Disk method

Mar 17 - Mar 23

Analysis of photometry - Integrate new data into old data - Any changes? - Migrate all the photometry plots to matplotlib

Plot EW stuff using Matplotlib
