... 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. ...

... The data was taken over many days with the same source in more than one file. ... You want to convert the data to kelvins (this is galactic work) and then average all the scans for each source. ... input each onscan, average, and then scale to kelvins . place all of the averaged scans in an array, when done with the file, store this array in an idl save file for this day. ... Average together scans of the same source and then baseline them. input all of the daily save files into a single array . ...

Next: Fitting the Blaze Up: Instrument Response Correction Previous: Instrument Response Correction . ... This flux has to be corrected for two effects in order to get absolute fluxes: first, for the echelle blaze effect, and second, for the chromatic response of the instrument. ... The solution adopted in the reduction, using the standard star љ , is to correct for both the blaze effect and the instrument response simultaneously. ...

... The first step to improve the FORS calibration is therefore to obtain data to allow a computation of the illumination correction across the field. ... Another limitation on the calibration accuracy has been the brightness of the Landolt standards which have forced the use of extremely short exposures introducing small but non-negligible shutter-time errors and also resulting in a very small number of useful standards per frame. ...

... 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. ...
