Comments and Error List for

The Observation and Analysis of Stellar Photospheres, 3^rd edition.

--- Please tell me at dfgray@uwo.ca about any errors you find ---

p. 12, Eq. 1.11: The dv at the end still has three components and might be written as d³v. The same is true in Eq. 1.12.

pp. 12 & 13: One may wish to call v₁, v₂, and v₃ speeds instead of velocities.

p. 28, Fig. 2.1: The star convolution sign between the top and middle panels should be a multiplications sign.

p. 40, Fig. 2.8: The star convolution sign between the Shaw function and F(x) to the left should be a multiplication sign.

p. 120, following Eq. 6.4: The numerical value of s should be 5.67040 x 10^-5 or 10^-8 to be consistent with the more correct value in Appendix A.

p. 131, Eq. 7.8: The integration variable at the end should be t_nu not tau_nu.

p. 142, four lines after Eq. 7.37: The density units should be g/cm³.

p. 149, last text line before Eq. 8.1: (1.16) should be (1.17).

p. 150, third line of text: Delete the I² in (hRc/I²).

p. 150, Eq. 8.3: For numerical computation, one would normally use the more precise value of 13.598 eV instead of 3.60 eV, as in Apendix D.

p. 172, second line up from bottom: Magnetic pressure is B²/(8pi). The B values in Table 9.1 should be increased by 2^1/2.

p. 173. Eq. 9.2: The delete the exponent of ½ on t₀ in the integrand. (A known error from the 2^nd edition that did not get fixed.)

p. 188, line 6-7: The wavelengths are reversed, as is clear from Fig. 9.10.

p. 188, line 8: The sixth word is supposed to be ‘depends.’

p. 191, Fig. 9.13 caption: Insert “In these relatively cool models, the electron pressure rises rapidly in the deep layers, where the electron doners become more ionized.”

p. 192, Fig. 9.14 caption: Replace with “Gas pressure and electron pressure are shown as a function of log tau₀ for models having S₀ = 2.0. For these relatively hot models, the electron doners are highly ionized resulting in P_e closely tracking P_g.”

p. 194, Fig. 9.16: The heavy curve should be labeled 1, not 0.

p. 195, four equations starting with 9.24: replace the c₀ symbols with the word constant. The point of these four equations is to specify the proportionality. The constant will be unique to each case.

p. 218, top of page: Delete this six-line paragraph.

p. 224. The sign of the bolometric correction has not been consistently handled here. Keeping the negative convention shown in Fig. 10.16 and Eqs. 10.9 & 10.10 means that the sign of BC in Eqs. 10.7 & 10.8 should be reversed.

p. 258, Fig. 11.10: In the ordinate label, the a off to the left should be the second argument in H(u,a).

p. 486, Fig. 18.22: The 5/3 at the end of the equation is supposed to be an exponent on the mass, as in Eq. 18.23.

p. 507, Table B.2: The effective temperatures for these giants come from Eq. 14.17 and should read as follows.
