Appendices B, C and E, which contain the surface photometry, the main catalogue and the summary catalogue respectively, are only available in electronic form. They can be obtained from Le Centre de Données astronomiques de Strasbourg (CDS) via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/Abstract.html

...Appendix A
These plots correspond to the first thirty unsaturated galaxies in the VPC, and have therefore been selected on the basis of their right ascensions alone.

...mean
The mean values being applicable to Virgo Fields A and B only. Due to significant de-sensitisation (as described in Sect. 7.1) of Fields C and D on Plate J4882, only Plate J9229 was used for objects lying in these two latter fields.

...D
Note that strictly speaking, due to the slight displacement between the J9229 and J4882 (x,y) coordinate systems, those images near to the boundaries of any field in one system may lie within a neighbouring field in the other system. In these cases and when a plate flaw rendered one plate unreliable for a particular object, whether a quoted magnitude was based on one or two plates depended on other factors. Individual cases can be checked in the VPC which quotes standard errors on the machine-generated (mean) 59#59 magnitudes only when two plates were used.

As with the mean standard errors on the colours quoted in the VPC, the lower values obtained for fainter objects may be due to limitations in the dynamic range of the COSMOS microdensitometer.

...Gaussian
To be rigorous, the resolution function is not of course a perfect Gaussian (or identical for different parts of any plate) but a Gaussian is still a good approximation.
