... The narrow emission-line template spectrum of NGC 5548 has for the first time enabled us to isolate the narrow and broad UV emission-lines and thereby determine firm estimates for the intensities of the broad emission-lines for both the low-state spectrum, and the average HST/FOS archival spectrum obtained from the intensive monitoring campaign undertaken by "AGN Watch" on April 19th 1993, when the continuum was a factor of ~4.8 brighter. ... huizinga@stsci.edu . ...

... While the resultant gains probably track the phase during the calibrator scan, what we are really interested in are the antenna gains for the program source. If you solved for a number of time intervals during the calibrator scan, the best guess at the antenna gains for the program source is derived by interpolating between some average of the calibrator scan gains. ...

Next: Equations of condition Up: Extinction and transformation Previous: Extinction and transformation . Bias can also be introduced by improper fitting procedures. For example, the reduction program known as SNOPY, used for many years at La Silla and also at La Palma, uses a simple iterative technique in which some subsets of the parameters are solved for, while others are held fixed; then the ones last solved for are held fixed, while the ones previously fixed are redetermined. ...
