In this section, I pick stars which were observed by two different TASS cameras in the same passband. On both axes, magnitudes are expressed in millimags. One can calculate numerical values for these differences, as well as plotting them. I suspect that this may be due to color terms between the I-band cameras. The mean differences are always less than the standard deviations, which is good.
All graphs show magnitudes in units of millimags.
None of the cameras appears to have a strong color term.
