Day 1-2 (07/11-12)

  • Day 1: Reviewed papers Chris sent, met with Chris and Eske on Zoom to discuss expectations, project outline on wiki page
  • Day 2: Set up FASRC account. Followed the "User Quick Start Guide" on FASRC page
    • set up 2FA, FASRC VPN, terminal access, and watched a few data transfer videos
    • Used rsync to load Eske's target directory /n/holystore01/LABS/stubbs_lab/Lab/Auxtel_data/spectrum_data onto computer
    • Went into lab and met Eske, Ali, and Mark in person. Very cool people.
    • Opened Jupyter notebook; looked up astropy documentation to open fits files
    • Successfully opened fits file to view contents inside, retrieved and displayed table data, displayed file header information, and plotted data

Day 3 (07/13)

  • In Jupyter notebook, filtered all the fits files in '/spectrum_data' to print out star name and date/time of observation
  • Stored names of files in record type that are all associated with one star; looks like there are 4 observed stars in the dataset Eske gave me.


Day 4 (07/14)

  • Found data files missing the table of equivalent widths that Eske gave me
  • spec_data_2022062800336.fits HD205905 2022-06-29
  • Plotted H2O and O2 equivalent widths against air masses for each star on each night (four stars on four nights based on data Eske gave me)
  • Noticed that some files do not have O2 data (may have variants like O2(Z) or O2(B), though)

First Impressions of Data:

  • The equivalent widths of H20 seem to have much more variability than those of O2
  • May be some outliers in the data (particularly for the first two plots with the negative equivalent widths, may need to check on those data points

  • Noted that I only have 187 files, I think Eske mentioned I should have access to a number of files in the 700 range. Will need to check with him on that.
  • Exported the data table as "faulty_files.csv" file that can be found herebelow. I might not pursue any further the conversion of pandas data frame to image.
