... 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. ...

Next: Running REDUCE/CCD Up: Processing the Data Previous: Processing the Data . Before any processing on the input frame is done, the REDUCE/CCD command will first collect all resources needed for the calibration of the science frame(s). These include the master calibration frames, the overscan offset, and scaling parameters. So, at this point no operations are done yet. ... As an example, suppose the science frame is supposed to be corrected for dark current and to be flat fielded. ...

... 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. ...

... The pinhole simulation program is a computationally and memory intensive task. ... A parallel version was developed instead, to enable distributed processing on a cluster of workstations. The program makes use of the Message Passing Interface (MPI) standard for parallel processing, implemented as an API (Application Programming Interface) to the Local Area Multicomputer (LAM) programming environment developed at the Ohio Supercomputer Center. ...
