... The routine processing of STIS data in the calibration ``pipeline" requires an interrelated set of software tasks and databases developed and maintained by many groups at STScI. We present the systems-level design of this calibration pipeline from the perspective of the STIS instrument group at STScI. We describe the multiple interfaces to the pipeline processes that the STIS group works across in an effort to provide for the routine calibration of STIS data. ... For example, the STIS group: . ...

... Since the reddening found for the stars in Table 13 was small, no reddening correction was attempted. ... These diamonds indicate the positions of very low mass, 3 Myr old, objects from the work of Burrows et al. ... This optical V versus R - I scheme is a very powerful method of detecting very low mass (VLM) objects. ... Because of this, young brown dwarfs are intrinsically no more difficult to observe in the optical than low mass stars at the age of Orionis. ...

Next: Conclusions Up: The Hamburg/SAO Survey for Previous: Non-classified objects . ... Since the main goal of the HSS is an efficient search for new BCGs, the fraction of this type among all new detected ELGs - 84 %, or 80 % among all emission-line objects, is very encouraging. ... Thus a large fraction of BCGs relative to all ELGs is found ( 78 %) demonstrating the high efficiency of this survey to find on the Hamburg Quasar Survey photoplates namely galaxies with H II -type spectra. ...
