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. <P> 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=<TT>'FORK'</TT>, 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''. <P> The column labels are the same as for the fork mount, but prefixed by <TT>TE</TT> for telescope east of the pier, and <TT>TW</TT> for telescope west; see Tables <A HREF="node590.html#tbl:german-ex">I.6</A> and <A HREF="node595.html#tbl:german-label">I.7</A>. <P> <BR> <DIV ALIGN="CENTER"><A NAME="30232"> </A> <TABLE> <CAPTION><STRONG>Table:</STRONG> Example of partial table contents for German equatorial mountings</CAPTION> <TR><TD> <DIV ALIGN="CENTER"> <TABLE CELLPADDING=3 BORDER="1" ALIGN="CENTER"> <TR><TD ALIGN="RIGHT"><TT> DEC</TT></TD> <TD ALIGN="CENTER"><TT> TEOBSE</TT></TD> <TD ALIGN="RIGHT"><TT> TEMOONE</TT></TD> <TD ALIGN="RIGHT"><TT> TEOBSW</TT></TD> <TD ALIGN="RIGHT"><TT> TEMOONW</TT></TD> <TD ALIGN="RIGHT"><TT> TWOBSE</TT></TD> <TD ALIGN="RIGHT"><TT> TWMOONE</TT></TD> <TD ALIGN="RIGHT"><TT> TWOBSW</TT></TD> <TD ALIGN="RIGHT"><TT> TWMOONW</TT></TD> </TR> <TR><TD ALIGN="RIGHT">+30.</TD> <TD ALIGN="CENTER">5.6</TD> <TD ALIGN="RIGHT">-84.5</TD> <TD ALIGN="RIGHT">109.3</TD> <TD ALIGN="RIGHT">119.1</TD> <TD ALIGN="RIGHT">285.4</TD> <TD ALIGN="RIGHT">283.5</TD> <TD ALIGN="RIGHT">6.3</TD> <TD ALIGN="RIGHT">99.1</TD> </TR> <TR><TD ALIGN="RIGHT">+20.</TD> <TD ALIGN="CENTER">5.3</TD> <TD ALIGN="RIGHT">-70.1</TD> <TD ALIGN="RIGHT">104.7</TD> <TD ALIGN="RIGHT">114.3</TD> <TD ALIGN="RIGHT">283.6</TD> <TD ALIGN="RIGHT">281.7</TD> <TD ALIGN="RIGHT">6.5</TD> <TD ALIGN="RIGHT">84.3</TD> </TR> <TR><TD ALIGN="RIGHT">+10.</TD> <TD ALIGN="CENTER">5.4</TD> <TD ALIGN="RIGHT">-76.8</TD> <TD ALIGN="RIGHT">104.7</TD> <TD ALIGN="RIGHT">106.1</TD> <TD ALIGN="RIGHT">280.3</TD> <TD ALIGN="RIGHT">279.1</TD> <TD ALIGN="RIGHT">6.7</TD> <TD ALIGN="RIGHT">79.5</TD> </TR> <TR><TD ALIGN="RIGHT">0.</TD> <TD ALIGN="CENTER">5.4</TD> <TD ALIGN="RIGHT">-78.6</TD> <TD ALIGN="RIGHT">88.0</TD> <TD ALIGN="RIGHT">89.5</TD> <TD ALIGN="RIGHT">275.4</TD> <TD ALIGN="RIGHT">272.5</TD> <TD ALIGN="RIGHT">6.3</TD> <TD ALIGN="RIGHT">79.2</TD> </TR> <TR><TD ALIGN="RIGHT">-10.</TD> <TD ALIGN="CENTER">5.7</TD> <TD ALIGN="RIGHT">-85.7</TD> <TD ALIGN="RIGHT">79.3</TD> <TD ALIGN="RIGHT">82.1</TD> <TD ALIGN="RIGHT">270.1</TD> <TD ALIGN="RIGHT">267.2</TD> <TD ALIGN="RIGHT">6.4</TD> <TD ALIGN="RIGHT">84.6</TD> </TR> </TABLE></DIV> <A NAME="tbl:german-ex"> </A></TD></TR> </TABLE> </DIV> <BR> <P> Table <A HREF="node590.html#tbl:german-ex">I.6</A> shows the table layout for German equatorials.
