Moves the TAURUS pupil plane filter wheel to the specified position.
Format: TPFILTER <position>
Range: <position> is an integer in the range --8 to 8 or the name of the filter.
Examples : TPFILTER 3 or TPFILTER HARRIS-V
Comments: There are 8 filter wheel positions. These can be selected either by specifying a number between --8 and 8, or by specifying the filter name. In normal operation the parameter should be positive. If the parameter is negative, the wheel will not be clamped on completion of the move, and the position of the wheel will become undefined. Note that position 1 is a large hole, used for accessing the etalon wheel, and cannot be used for mounting filters.
