This Read Me is an attempt to help the user walk through the process that was implemented for Spectral SNe Analysis in Summer 2019. STSci Summer internship
Contents:
- Red Shift Calibration
- Emission Calculations
- Intensity Computation
Before completeing steps, organize by putting all observations of SNe into one directory and one directory per SNe.
- This step is used to plot the spectra and confirm accurate redshift and rest wavelength obtained. This can be skipped if confidently known. -Using code; SNe.Redshift.py -Execute Code - > directory input. (ex. /Users/Documents/SNe.Analysis/Data) Note* Can change file extesion type on line 16 -> designate one or all observations -> plot generated.
**Here you can use the vertical lines which are identifying Helium and H-alpha lines to confirm accurate rest wavelength.
- This step is the process of using Q-SIC and is accompanied by 4 different codes that distribute 17 emission lines of interest. Repeat Steps for each code. -Using codes; SNe.QSIC.1.py - SNe.QSIC.4.py -Execute Code - > Directory input. (ex. /Users/Documents/SNe.Analysis/Data) -> code will generate plot with vertical lines identifying the 4-3 emisson lines of interest. Use this to identify the start and end wavelengths to run the calculator. -> Next, will designate and ask for the input of identified start/end wavelengths. Note* Input needs to be with a space between the two wavelengths and in Angstroms. (ex. 6563 7410) -> code will automatically output the calcuation of Equivalent Width and Continuum in two seperate .txt files.
**It is important to know that there must be data in the identified wavelengths or the code will throw a warning.
- This final step takes the 4 seperate out put files from step 2, runs the computation to calculate the Intesity and outputs the calculation as a text file.
- Using Code; SNe.join.py Before execution, the user needs to input desired directory into the code manually, @ line 5. -> Execute Code - > Output Calculation as .txt files.
