MOUNTING='GERMAN'

The independent variable (i.e., the reference column of the table) is labelled DEC, and contains the declination in degrees. The table entries are the hour-angles of the various limits, measured in decimal degrees. All angles should be accurate to about 0.1 degree.

These asymmetrical mountings suffer different obscurations and mechanical limits when the telescope is east of the pier and west of the pier, so it is necessary to have a double-sized table. Each half of the table corresponds to the whole of a fork-mount table, but for a particular side of the pier. Therefore, you should read the detailed description in the previous section, for MOUNTING='FORK', before gathering the data for a German equatorial. It will probably be most convenient to gather all the data for the ``telescope east of pier'' position, and then all those for ``telescope west''.

The column labels are the same as for the fork mount, but prefixed by TE for telescope east of the pier, and TW for telescope west; see Tables I.6 and I.7.

Table I.6 shows the table layout for German equatorials. Each column is described in detail below; see Table I.7. See section I.4.3 on fork-mounts for more detailed discussions of the quantities in the table, as the entries are basically the same for both types of mounting.
