3 Reduction and calibrations

All details on the common protocol, the preparatory work on the frames as well as a description of the used reduction procedures can be found in Paper I. The reduction method, developed and discussed by Cuypers (1997), is specifically adapted to double-star imaging. The reason for a dedicated method is the regular absence of a single well-exposed point-spread function (PSF) reference star on the frames and the fact that the profiles of the components overlap when their separation is small. We first determined the background by taking the median of three of the four corner values of each frame. After sky subtraction, a generalized and unique Moffat PSF was fit to all the components simultaneously. A set of calibrator stars or "astrometric standards'' has been regularly observed. These data together with the trails of bright objects are used to determine preliminary estimates of the scale and orientation values. In addition, these regularly observed astrometric standard stars allow valuable consistency tests for both the astrometry and the photometry (cf. Sect. 6). The final calibration of the scale and the orientation per CCD and per mission has been achieved at the level of 0.01% in scale and 0.07$^\circ$ in orientation by a careful comparison with the Hipparcos results (Oblak et al. 1997). An independent way of obtaining such accurate scale and orientation values (i.e. seeing independent as opposite to the method of the trailed images) consists in using astrometric standard fields located in well-studied but dense (open) clusters (e.g. Le Campion et al. 1996).

The transformation coefficients are listed together with the extinction coefficients for each night of "reasonable'' photometric quality in Table 1. The tabulated coefficients were computed by fitting the following models using a classical least squares method: Model 1 (with a non-linear colour dependence, bracketted in Table 1 and mainly significant in the filter V):

$$\begin{eqnarray*}{\rm mag}_{i,{\rm st}} =&& {\rm mag}_{i,{\rm obs}} + k_{i,1}. F_{z} + k_{i,2}. (V-I) \\ &&+ k_{i,3}. (V-I)^{2} + C, \end{eqnarray*}$$

where k_i,1 is the extinction for the filter i, k_i,2 and k_i,3 the colour terms, F_z the airmass, (V-I) the (known) standard colour index and C the offset in magnitude; Model 3 (where two or more nights were treated together):

$$\begin{eqnarray*}{\rm mag}_{i,j,{\rm st}} = {\rm mag}_{i,{\rm obs}} + k_{i,j,1}. F_{z} + k_{i,2}. (V-I) + C, \end{eqnarray*}$$

where k_i,j,1 is the extinction for the filter i and for the night j while k_i,2 is the (unique) colour term; Model 5 (where two or more nights were treated together and a non-linear colour dependence was applied):

$$\begin{eqnarray*}{\rm mag}_{i,j,{\rm st}} &=& {\rm mag}_{i,{\rm obs}} + k_{i,j,1... ...i,3}. (V-I) + C, \\ &&\qquad\quad {\rm for }\quad (V-I) \geq 0.7 \end{eqnarray*}$$

where k_i,j,1 is the extinction for the filter i and for the night j while k_i,2 and k_i,3 are the two colour terms. In all these previous equations "mag'' stands for both magnitudes V,st and I,st. Models 3 and 5 were used when not enough standard stars in a single night had been measured or when the photometric quality during a small portion of a night was not guaranteed due to passing clouds, thereby allowing the transformation of a larger amount of differential data (thus defining the term reasonable photometric conditions). In these cases the transformation errors were assumed to be at least twice as large as computed from the fit. In the mean external errors as deduced from the residuals of the standard star data are seldomly larger than 0.03 mag. Such errors must be considered as safe upper limits. These values imply conditions which were not of the same (excellent) quality as the 1991-92 runs by Cuypers & Seggewiss (1999) as they obtained lower external errors of at most 0.02 mag (Paper II). One should mention that due to the secular effects of the Pinatubo eruption in 1991 the extinction coefficients are much larger than usual. In fact one may easily follow the evolution with time in the listed values of Table 1, where a decrease with a factor of two can be seen between the value for the extinction in August 92 and the one of November 94. From the measurements obtained in the Geneva photometric system a mean extinction value in V of $0.147 \pm 0.014$ can be deduced, in very good agreement with the values for December 93 found in Table 1. A problem has however been detected while modelizing the transformation equations for the December 93 mission: inspection shows an anomaly in the sense that $k_{i} \simeq k_{V}$ and that the colour term is large. But the inclusion of an additional colour term allowed to obtain a good fit on the standard values and to take the effect of a probable filter mismatch into consideration. No systematic differences appeared between these measurements and the ones obtained during the rest of the campaigns. Although regularly measured and adopted as a secondary standard star (Clausen et al. 1997 give $\sigma_{V} = 0.006$ mag), we found on one occasion, during a night of good photometric stability, a possible variation at the level of a few hundreths of a magnitude in the V measurements of HD 7040 as shown in Table 2. The close proximity and faintness of a newly detected companion at a separation of $\sim$3.3 $^{\prime \prime }$ (cf. Table 3) is here certainly not in cause.
