Next: Line Identification Up: Getting the Dispersion Previous: Getting the Dispersion . The first step consists of detecting the emission lines of the comparison spectrum to produce the line table line.tbl . It can be noted that the command SAVE/LONG will store all keyword values as descriptors of this table, so that a session can be saved only if the table line.tbl is available. ... Midas.. ... SEARCH/LONG . ... The detections are stored in the following columns of the table line.tbl : . ...

Next: Determination of atmospheric parameters Up: Optical spectrum of IRAS04296 Previous: Radial velocity of the . From comparison of observed and synthetic spectra of IRAS04296 we revealed some strong absorptional features whose positions coincide with known diffuse interstellar bands (DIBs) (Jenniskens et al., ... In Fig. 5 we illustrate the presence of DIB's by showing a spectral region of IRAS04296 . ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... Top panel: comparison between the observed H and H line profile (black solid line) and synthetic profiles calculated with the final adopted parameters (dash-dotted green line) and with the parameters which were found to best fit the hydrogen line profiles (dashed red line). ... We provide photometric and spectroscopic evidence showing the star is most likely a member of the young Stock 16 open cluster (age 3тАУ8 Myr). ...

Calibration of the GHRS . The GHRS has a spectrum calibration lamp which is used by specifying SC2 as the aperture with WAVE as the target. ... The lines are bright enough so that a 30 to 60 second exposure will yield a good comparison spectrum at almost any wavelength, although longer times are needed at some echelle settings. ... Also, wavelength calibration exposures are generally used to just confirm the zero-point of the spectrum and not to obtain a full wavelength solution. ...

... The HST uses an onboard model of its orbit to perform in real-time various control functions relating to spacecraft operations and observation support. ... New coefficients for the ephemeris are updated every other day, and are archived as FITS keywords for each HST observation data set. Using these coefficients,an observer can perform a variety of calibration and characterization calculations relating to the orbital position and velocity of the telescope. ...

... Data Handling and Products > Data Reduction FAQ > The spectrum of my MOS flux standard star is shifted in wavelength by several pixels. Why is that and how can I correct for it? ... Observing with ESO Telescopes . ... The shift of the flux standard spectrum is caused by a combination of bad centering within the slit and possible wavelength calibration issues. To align the spectrum to the tabulated flux, use the parameter --resp_shift in vmmosscience when determining the response curve. ...
