-\tbd{we will provide a new airmass function}
-
-The airmass is calculated using the SLALIB function \code{sla_AIRMAS}.
-
-The parallactic angle is calculated using the SLALIB function \code{sla_PA}.
-
-%The parallax factors are calculated using the following formulae
-%(Smart et al.\ 2003, A\&A, 404, 317):
-%\begin{eqnarray}
-%P_\xi & = & \cos \alpha \sin \lambda \cos \epsilon - \sin \alpha \cos \lambda \\
-%P_\eta & = & (\sin \epsilon \cos \delta - \cos \epsilon \sin \alpha \sin \delta) \sin \lambda - \cos \alpha \sin \delta \cos \lambda
-%\end{eqnarray}
-%where $\alpha$ is the Right Ascension, $\delta$ is the Declination,
-%$\lambda$ is the solar longitude, and $\epsilon = 23^\circ 27'08''.26$
-%is the inclination of the ecliptic.  The solar longitude is obtained
-%from the ecliptic coordinates of the Sun.
-
-\tbd{we will provide a new mean-to-apparent conversion}
-
-To calculate the parallax factors, get the mean-to-apparent parameters
-(\code{sla_MAPPA}) for a mean epoch of 2000.0, and, given the mean
-position of interest, calculate the apparent position
-(\code{sla_MAPQK}) for a parallax of 1.0 arcsec $(\alpha_1,\delta_1)$,
-and a parallax of 0.0 arcsec $(\alpha_0,\delta_0)$.  Then the parallax
-factors in radians are:
-\begin{eqnarray}
-P_x & = & 3,600 (180^\circ/\pi) (\alpha_1 - \alpha_0) cos (\delta_0) \\
-P_y & = & 3,600 (180^\circ/\pi) (\delta_1 - \delta_0)
-\end{eqnarray}

-\tbd{ephemerides code to replace this?}
-
-The SLALIB function \code{SLA_RDPLAN} returns the apparent position of
-a specified planet, or the Moon.
-
-To calculate the position of the Sun, use \code{sla_EVP} to get the
-position of the earth relative to the Sun, and convert from the
-cartesian coordinates to spherical using \code{sla_DCC2S}, and
-calculate the position on the opposite side of the sphere ($\alpha
-\rightarrow \alpha + 12 {\rm hrs}$ and $\delta \rightarrow -\delta$).
