7. Preparing your Data
... Before you calibrate, you must prepare your data. This consists of loading, flagging, perhaps converting to ``channel-0'' datasets, and then splitting. ... Tracking accuracy: the tracking accuracy of the ATCA antenna is usually adequate at low frequencies, but at higher frequencies (where the primary beam is smaller), tracking errors become more deleterious. ... In addition, poor tuning of the antenna drive systems can sometimes cause poor tracking, particularly after a source change. ...

10. On the problem of high spectral resolution observations of faint objects
... December 21, 1997 . ... Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...

12. Indexing and Searching Distributed Astronomical Data Archives
... The technology needed to implement a Distributed Astronomical Data Archive (DADA) is available today (e.g., Fullton 1993). Query interface standards are needed, however, before the DADA information will be discoverable. ... These parameters would be used to index each dataset in each catalog. ... The technology is available today to perform cross-catalog queries, to fetch the data at the click of a mouse, quickly to add new observation catalogs, and to distribute the load across multiple machines. ...
