Next: Results of follow-up spectroscopy Up: Data reduction Previous: Reduction of the Calar . In the final spectra, redshifts and line fluxes are measured within MIDAS, applying Gaussian fitting to the emission lines. To determine redshifts for individual galaxies, averages are taken over the prominent individual emission lines (mostly H , H , [O III ] 4959,5007 ?) The line [O II ] 3727 ? ... For all spectra, the individual emission line fluxes of the H , [N II ] 6548,6583 ? ...

On this page, we describe what the phase correction algorithms set out to do and the framework we have developed to optimally use all of the available information. ... We are developing a Bayesian framework to combine all the information we have about the current and future meterological conditions (which are naturally accommodated as priors in a Bayesian scheme) with detailed physical models of the atmosphere. ...

Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...

... As modern observatories evolve to production units delivering data products and calibrated scientific data to the end users, new challenges arise in assessing the quality of data products. ... Taking the analogy of speed control on a motorway we can describe the system as a device (radar) collecting measurements of the system performance (passing cars). ... One of the direct applications of quality control is the verification of instrument performance based on the analysis of calibration exposures. ...

... Impedance . Electrical impedance, or simply impedance, describes a measure of opposition to a sinusoidal alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. ... Resistance is the real part of impedance; a device with a purely resistive impedance exhibits no phase shift between the voltage and current. ...

... After the data from an observation have been received and processed through the STScI pipeline, hardcopy products ( paper products ) are generated which summarize the data obtained. ... Paper products typically summarize the set of exposures that constitute a visit in the Phase II proposal. ... The content of the pages is as follows: . ... Observation Summary: a table summarizing the proposal information for each exposure in the present set, including processing and data quality flags ( Figure 15.4 ...
