Modify the Task 2 & 7 section of the script so that it performs the red shift calculation on the second star in spectra, not the sixth.
I have changed s to the second column (s= spectra(:,2)), and that is right.
How do I get the correct values of lambdaHa and speed?

s = spectra(:,2)
[sHa,idx] = min(s)
lambdaHa = lambda(idx)
z = lambdaHa/656.28 - 1
speed = z*299792.458

tast 2 & 7
s=spectra(:,2)
Did you store the second column of spectra in s?------> this error is not remove..why?

Could some kindly help me with Tasks 2&7 on the MATLAB Onramp on the topic "Project > Stella Motion"?
Here is my answer:
s = spectra(:,2)
[sHa, idx] = min(s)
lambdaHa = lambda(idx)
z = (lambdaHa/656.28) - 1
speed = z*299792.458
I cannot go further beyond this point. Many thanks.

[sHa,idx]=min(s)
lambdaHa=lambda(idx)
hold on
x=lambdaHa
y=sHa
plot(x,y,'rs','MarkerSize',8)

Hi,
The correct values for lambdaHa and speed are calculated using Task 4. At every Task whole of the script runs not the portion of the same.
Thanks

[sHa,idx] = min(spectra(:,2))
to
[sHa,idx] = min(spectra)

how will be the next step's code?
Did you add a point to the existing axes?
Add a point to the existing axes by plotting x = lambdaHa, y = sHa as a red square ("rs") with a marker size ("MarkerSize") of 8.

Modify the Task 2 & 7 section of the script so that it performs the redshift calculation on the second star in spectra, not the sixth.
