Geneva Photometric Boxes. IV. A Refined Method for Direct Access
In the Geneva photometry, a photometric box around a socalled central star is the set of stars having almost the same colours as this central star.
For the most current applications, it is useful to construct the boxes of a few hundred stars. A method allowing to obtain these boxes rapidly is described. It is based on so-called direct access square files. A FORTRAN routine on a UNIVAC 1160 computer is widely used at the Geneva Observatory. The principles described in this paper may be easily adapted to build square files and to write routines in evolved languages for most computers.
Other applications of square files are also outlined.
