1. The spectrograph design and the observing procedure
... The choice of the spectrograph design (Fig.2) is determined by the quantity R, the overall dimensions of the PF cage and the restrictions on the rigidity of the structure of the device. ... As the camera's objective a fast 4-lens aplanat is used having a focal distance F cam =140 mm and a relative aperture of 1:1.8, the resolution at the centre is no less than 80 gr/mm, that over the field at a distance of 3 mm from the edge along the frame ( ) diagonal is 35 gr/mm. ...

13. Description
... The motivation for this task is to create one high resolution response matrix for a set of observations without the need for creating individual high resolution matrices. ... This task creates a single response matrix file using information from a list of spectrum from multiple observations, and can also combine spectra and background spectra of the same instrument and spectral order to produce final files that can be used for futher, quantitative analysis in a fitting package such as Xspec. ...

... No flares were detected during the 3.5 hours of monitoring. ... The resultant spectrum was of sufficient quality to allow the detection of emission lines with an integrated flux of 10$^{-15}$ erg cm$^{-2}$ s$^{-1}$ or greater. Lines of C I, O I, O V, Cl I and Fe XXXI were detected. ... From the upper limit on the observed line width, we derive an upper limit of 38 km s$^{-1}$ for the turbulent velocity in the 10$^{7}$ K plasma. ...

17. On the Combination of Undersampled Multiframes
... In order to overcome undersampling, two or more frames of the same field may be obtained which are shifted with respect to each other by fractions of a pixel. ... Obviously science programs such as photometry of dense star fields and the morphological classification of distant galaxies would benefit from a method allowing a proper combination of two or more ``dithered'' WFPC-2 frames, i.e., frames that are shifted with respect to each other by fractions of a pixel. ...

... Equivalent widths of Ca I absorption lines at 6122?, 6162?, and 6494? and Fe I at 6103?, 6200?, and 6574? were measured for several spectral standards. ... The spectral types of the target stars were determined by comparing source line ratios to those of standard stars. ... The uncertainty in the spectral type is about one and a half sub--types. ... Northwest of the belt, again all but one source shows Li in absorption, but only one star (out of 13 = 7.7%) shows an H emission line. ...
