... specadd creates a multiple X-ray spectrum FITS file by stacking or putting together (``adding'') two single spectrum files. ... This type of spectral files is particularly useful when the user wants to simultaneously analyse different observations of the same object carried out with the same instrument or with different instruments. ... The Data extension for a multiple spectral dataset stores one single spectrum per row, instead of one channel per row as it is the case of single spectrum files. ...

GENERAL DESCRIPTION OF DATABASE . It is a matter of common knoledge, that solar magnetic fields and, in particular, magnetic fields of sunspots, play important role in many solar events. In Pulkovo observatory the long-term data set of daily observations of magnetic fields of solar sunspots was accumulated, which contains great potential for further researches in solar physics. ... Second section includes files containing sum data about magnetic fields for every observational day. ...

... This review presents the results of Scenario Machine computations aimed at the population synthesis of different types of binary stars in our Galaxy and another galaxies. They demonstrate the ability of this method to make an important gross analysis of the modern scenarios for binary evolution, as well as to give interesting qualitative and quantitative predictions which can be checked observationally. ... The future development of the method can be considered from two different points of view. ...

Next: Echelle Reduction Method Up: No Title Previous: Example . This Chapter provides the basic information necessary to understand the echelle љ package implemented in MIDAS . ... Tutorial examples are available in the system (command TUTORIAL/ECHELLE ) and are also included in the Appendix so that users without previous experience in MIDAS could become familiar with the calibration procedures. ... The methods described here are generally sufficient to cover a wide range of echelle formats. ...

... SFIT is a general-purpose code designed to optimize theoretical stellar spectra to an observed spectrum. ... While the programme expects input from "stdio", it is more natural to save commands in a file (eg "sfit_input") and run the code simply by . ... If the spectra to be fitted have a filename "star_spectrum", then the best fit spectrum will be written out, together with the renormalized input spectrum, to a file called "star_spectrum.fit". ... sets up model spectrum grid (and for 2nd star) . ...

... Press Releases . ... Release Notes . ... All of the functionality of PyFITS is now available in Astropy as the astropy.io.fits package, which is now publicly available. Although we will continue to release PyFITS separately in the short term, including any critical bug fixes, we will eventually stop releasing new versions of PyFITS as a stand-alone product. ... Prior to PyFITS version 2.0 and beginning again with PyFITS version 2.3.1 (June 3 2010) PyFITS is covered under a BSD license. ...

... Information about a variety of different calendars for different cultures (e.g., Christian, Jewish, Muslim, Chinese, Hindu etc.) ... In addition, the Chinese had two different ways of interpreting and observing celestial events. One way the Chinese used astronomy was known as lifa; it was a discipline that aimed to understand the regularities and the predictable events in the celestial system through careful, observations, measurements and records. ... back to Teachers' Newsletter Main Page ...

. There are several different shells available for Unix; the most popular are described here. You can use any one of these shells if they are available on your system. And you can switch between the different shells once you have found out if they are available. Bourne shell (sh) . C shell (csh) . TC shell (tcsh) . Korn shell (ksh) . Bourne Again SHell (bash) .
