As the tanker moves its body acquires charge due to continuous rubbing by dust and air. If not removed, this static charge can cause spark and hence fire. The metallic chain ensures that all such charge flows to the ground.

An observer uses the and filters to obtain four exposures of the same field atdifferent air masses: two B exposures at air masses 1.05 and and two exposures at air masses 1.10 and Four stars in this field are photometricstandards. Their standard magnitudes are given in the table below, as are the instru-mental magnitudes in each frame.(a) Compute the extinction coefficients for the instrumental system: and Hint: at each air mass, Equation (10.10) holds. Write an equation for the difference between the magnitudes at the two air masses (e.g. an equation for ). Examination of this equation will suggest a method for computing the coefficients. You may find it helpful to enter the data from the table into a spreadsheet in performing the computations.(b) Compute the instrumental magnitudes of each star at zero air mass(c) Compute the transformation coefficients, and using themethod outlined in Section 10.7
