Photometry table in 'Source.py'

[ppathak8]

• Just a comment, the zero point value for the I-band is 30% more compared to what I get in my calculation.
• The values for other I-filters (I1, I2, I3, ..), seems to be fixed: 2.7e12
• elsewhere in the code I don't see the use of filter bandwidth, which can account for this discrepancy.

Can you let me know, if I am missing something?

Hi,
_ The values were imported from the OOMAO standard photometry class so there might be a few discrepancy, especially on the zero-point (We usually consider the number of photon per sub-aperture, not so much the magnitude).
_ The bandwidth is indeed not used in the code, everything is considered to be monochromatic around the central wavelenght specified in the photometry class.
_ if you need, you can also redefine another photometry class with your own values

Yes, I had looked up OOMAO, and I found the same there as well.

• The number of photons will vary with magnitude, which is correctly calculated.
• If it is monochromatic then it's fine, but this will impact the correct value of photons per sub-aperture you get for other bands of "I".

Indeed,
If you have the correct values, feel free to create a pull request to update the current values.

Will do it in the coming months.

Hi there, It seems this change introduced a couple indentation errors in Source.py. I made a PR to fix it.
