Observatory table

The standard ESO observatory table, called esotel.tbl, is stored in the MIDAS directory system at $MID_PEPSYS/esotel.tbl . This directory is not distributed with the regular MIDAS updates, but is part of the calib directory that can be reached by anonymous ftp from mc3.hq.eso.org (see the Dec. 1991 issue of the Courier for details). Just cd to the midaspub directory, and see the README file there. These table files must be installed on your local system before they can be used; there are procedures for creating them in the calib directory. These and other files in the calib directory subtree can also be obtained on tape by special request.

This is a short table, so if you need to make up a new one, just copy the ESO table and edit the copy with the EDIT/TABLE command. (If you do this, don't forget to change the descriptors as well as the table entries!) Or, using the dummy format file $MIDASHOME/$MIDVERS/contrib/pepsys/lib/esotel.fmt to convert a *.dat file to MIDAS table form, you could create a whole new table. The absolutely essential columns are the designation of the telescope focus, accurate coordinates (including height above sea level), and the diameter of the telescope. Please consult the Appendix to clarify the meaning of the more obscure columns! They are not yet required by PEPSYS, but may be in the future.
