Contents of this User Manual and References

This document explains procedures for observation preparation, and the usual operation and data reduction tasks to be employed by HDS users in the open use phase. In Section , the structure and performance of the spectrograph and pre-slit instruments (e.g., image rotators, calibration sources) are described. The parameters users need to specify for setup of the instrument are described in Section , as well as the methods needed to determine the parameters and the exposure time. The tasks that users need to carry out during observation and the format of CCD data obtained with HDS are described in Section .

The tasks that HDS users need to carry out include the specification of the HDS setup, the exposure times for astronomical targets, and the identification of the calibration data required. The operation of the telescope and the instrument will actually be performed by operators located at the observatory. See HDS Operation Manual (T.B.D.) for details of the operation of HDS, and High Dispersion Spectrograph (HDS) - Optical and Mechanical Designs for details of the structure of the instrument.
