For this exercise we will plot the stars in the constellation Orion both by hands and then in Colabs using matplotlib. Read “Lab-StarsInOrion.pdf”. (You can find it in our lab package by clicking on the link under Syllabus.) Create a diagram for the stars in Orion, just the PRESENT. Do this by hand using the chart in the lab. Take picture and insert it to your Colab notebook and/or submit the picture directly to Canvas.
Next you need to plot the same stars in Orion in Google Colabs using matplotlib. Watch and this tutorial on matplotlib:
You can follow the example below to plot Stars in Orion in Colab or Jupyter notebook:
You need to convert RA real number. For example, 5hr 54min = 5 + (54/60) = 5.9hr. RA = x, and DEC = y. Notice you have to invert the RA. This is because the RA starts high then goes lower.
Watch the same “Python Essential” and do a ~ 1 page summary on Sections 5, 6
Finally answer this math question (2 points): if a radio wave has a frequency of 100*10^6 Hz, what is it wavelength? Remember the wavelength and frequency inverse relationship for light.
Submit these to Canvas. You should have three items: (1) Stars in Orion graph by hand. (2) Stars in Orion plot using matplotlib. (3) Answer to math question.
