... It can · · obtain ice sample from 20 cm or deeper surface layer, then melt it and extract biomass from the ice surface water by filtration; Laser TOF MS for the measurements of element composition of the biomass; Gas TOF MS for the detection of: 1) volatile components, generated at the heating of biomass sample (closed window mode); 2) secondary ions , emitted from ice matrix by the influence of energetic magnetosphere ... Spectrum of yeast sample. ... Laser TOF MS 6. ...

... HST . ... The continuing difference, apparent after day 350, between the phase retrieval/Encircled Energy and plate scale results for camera 3 seems to indicate that the focus change was induced by a process not related to detector motion with respect to the Field Divider Assembly (FDA) because the part of the focus change caused by that motion is well tracked by plate scale changes. ... Encircled Energy provides a direct measurement of the focus position and absolute variations in focus position. ...

... Science . ... Science Users Information > Science Publications > Science Announcements > Processed Calibration Files for VLT instruments Now Available . ... ESO Data . ... ESOReflex data reduction workflows can be used to customize the generation of the processed and co-added calibration frames and to apply them to the science files. A detailed step-by-step guide on how to automatically associate the appropriate calibrations, raw or processed, to the science files of interest is available . ...

... The various Inst :Focus scripts allow you to take a series of exposures over a range of secondary mirror focus values, report the resulting FWHMs and optionally adjust the focus to the estimated best value. ... Slitviewer scripts assume the focus star is on the boresight. ... Focus scripts runs in three phases: . ... The script moves the boresight so the focus star is visible next to the slit, sets the focus to Center Focus, takes an exposure and tries to measure the star's FWHM. ...

Next: The ESO VLT CCD Detectors Software . ... Up: Instrument-Specific Software . ... The framework for data calibration and analysis of the VLT instrumentation is presented, based on the concepts of a calibration plan, pipeline calibration, quality control, and archiving of calibrated data for a ground-based observatory. ... Quality Control Pipeline provides quality assessment for instrument performance data and observing conditions, and tests the results of the Reduction Pipeline. ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...
