... The measurements themselves should be stored in a column with the label SIGNAL. ... Programs will expect that SIGNAL represents the integration of the photon flux for the exposure time given in the EXPTIME column (see section ). ... In that case, the column label should be RAWMAG; see Table . Programs will expect RAWMAG to be the usual negative logarithms of intensities; that is, RAWMAG values only use EXPTIME in determining weights. ...

... In combining the data, it is assumed that the low resolution image better represents the short spacing data, whereas the high resolution best represents the fine structure. ... Key: out The output image. ... Key: factor The flux calibration factor. ... In practise, the calibration may not be perfect, and an extra calibration factor will be required to align the flux scales. "factor" gives the factor to scale the low resolution image to put it on the same flux scale as the high resolution image. ...

On the command line, filters of the PROS type on QPOE files must be specified within quotes. e.g. im> imcopy "xdata$rp110590.qp[pi=2:10]" foo.imh # the input file # is rp90.imh . ...

... Next: The PROS Big Up: Software Systems Previous: Data Reduction Software . ... The srcinten task provides PROS users with a tool to compute count rates for point sources in the ROSAT High Resolution Imager (HRI). ... Corrected upper limits are cited at locations where the count rate falls below the source detection threshold. ... Srcinten is a new PROS task that computes and applies the above correction factors to the net counts in a user-specified aperture. ...

... The task lccorr takes, as its input, source and (optionally) local-background timeseries (TS) created by evselect , in which the time variation of the flux is represented by counts within time bins of equal duration. The main task of lccorr is to correct these time series for losses in flux due to a number of causes (exposure correction); these corrections are described in subsections 3.3 and 3.4 . ... Exposure corrections - introduction: . ... Correction of non-point-source time series: . ...

... A hundred years later, a handful of Tunguska-sized asteroids have been spotted by telescopes, but most remain unseen. The asteroid designated 2008 TC3 , which made the news on October 6th before colliding with the Earth on October 7th was too small to constitute a part of the "Earth impact hazard". ... 2008 TC3, for example, finally exploded in the atmosphere above Sudan . ...

... The experience of determination of the link between radio sources and dynamical reference frames is presented. To obtain this connection we used a series of very long baseline interferometry (VLBI) observations of the spacecraft Phobos-2 and angularly nearby quasars. ... The dynamical reference frame is determined by equator and equinox of these ephemerides. ... References . ... The relative orientation of the radio and dynamical reference frames can be described by a sequence of three rotations . ...

Arecibo Proposal No. ... And I guess the primary one-dimensional message is more understandable by unfamiliar aliens and the music is the most universal expression of intellectual activity by means of one-channel ear-like radio link. ... So, I suggest to implement the 1st Theremin Concert for Aliens from Arecibo or Evpatoria Radar facility. ... There were four Messages from Earth to proposed aliens -- two material (Pioneer Plaque and Voyager Record) and two ethereal (Arecibo-1974 and Evpatoria-1999). ...

This directory contains Calgary Neutron Monitor Data at five minute resolution. Each file is a gzipped tar archive that contains files of uncorrected count rates and barometric pressures at five minute intervals for one year. A file named snm.calg.fmi.YYYY.tgz is an archive that holds five minute data for the year YYYY. ... So a file named cal01030.fmi contains five minute uncorrected data for year 2001 day 30 (which is Jan 30, 2001). ... A text file named note.txt is also usually present. ...

... Two high school students from Texas and Louisiana are the winners of the 2012 Priscilla and Bart Bok Awards for their astronomy projects presented at the Intel Science and Engineering Fair in Pittsburgh, Pennsylvania in May. The awards were presented on May 18 by the Astronomical Society of the Pacific (ASP) in partnership with the American Astronomical Society (AAS), supported by funding from the National Science Foundation (NSF). ... The Bok prize is named for Bart and Priscilla Bok. ...

... When the strip that contained the galaxy was bandpass corrected, a negative image of the galaxy was present for the entire strip. ... If a continuum source drifted through the beam during this time, the cal deflection would be contaminated. ... The continuum source peaks at strip sample 67. ... You could take more samples (a longer strip) or remove the continuum sources before computing the bandpass correction. ... Top image. ... The bandpass correction does not contain any of the continuum source. ...

. This colorful display shows tiny differences (or "anisotropies") in the cosmic microwave background over the entire sky. The average temperature is just 2.73 kelvins (2.73 degrees Celsius above absolute zero), and the temperature differences represented here span mere millionths of a degree. Red represents the warmest locations, while blue reveals the coldest spots. These tiny temperature variations map the structure of the early universe. NASA / WMAP Science Team
