All Tables

Table 1: List of observed QSOs. Redshifts for the QSOs reported in the literature (Col. 3) are compared to the redshift determined from the IFS data cube (Col. 4). The "-'' signs correspond to data where we could not reliably determine the QSO redshift from the emission lines in the IFS data cubes. Redshifts are derived from the vacuum corrected wavelengths. Column 5 gives the QSO magnitudes in the Vega system, and Col. 6 the seeing in arcseconds measured in the data cubes. Column 7 lists the total integration time and the last column is the class of object defined from radio observations.
Table 2: Log of the observations. The last two columns show the average seeing during the integrations and the photometric conditions, respectively.
Table 3: Properties of the Ly $\alpha$ nebulae around the QSOs. Columns (1) list the names, (2) the redshifts derived from the narrow emission lines, (3) velocity offsets in the EELRs relative to the QSO redshifts, (4) peak surface brightness, (5) apparent extension of the Ly $\alpha$ nebula, (6) total Ly $\alpha$ flux from the nebula, (7) total luminosity in the nebulae, (8) emission line FWHM corrected for instrumental resolution, (9) relative velocity offsets between the narrow emission lines (one-dimensional spectra) and the QSO redshifts. Fluxes have been corrected for Galactic reddening. An analysis of the surface brightness has been attempted only for the two objects with very bright nebulae.
Table 4: Generalised Kendall's test probabilities for the null hypothesis that no relation exists between any two given quantities. The sample includes the IFS objects and the RLQs in H91b. The values in brackets give the correlation coefficients. The observed properties involved here are: the total luminosity in Ly $\alpha$ in the EELRs ( $L_{{\rm Ly\alpha ,neb}}$ ), the flux from the QSOs in the broad Ly $\alpha$ line ( $L_{{\rm Ly\alpha ,QSO}}$ ), the maximum extension of the Ly $\alpha$ nebulae (size), the quasar luminosities estimated at the rest-frame 912 Å ( $L_{{\rm Ly\alpha,912~{\AA}}}$ ).
