... Kepler is a mission designed to detect and characterize Earth-sized planets around solar-like stars. The sizes of the planets are determined from the decrease in light from a star that occurs during planetary transits, and the orbital period is determined from the repeatability of the transits. ... These goals are accomplished by continuously and simultaneously monitoring a single field of 140,000 stars for evidence of brightness changes caused by transits of Earth-sized or larger planets. ...

... This task computes the earth-satellite-target angle (EST) and the sun-earth-satellite angle (SES). The output is a table containing the time-history of these angles. cl> xray xr> xproto xp> evalvg xdata$rp110590r00 rp110590 Creating output file: rp110590_ang.tab . The output table contains four columns: spacecraft time (sc_time), EST angle, SES angle, OBI number. ...

... The input string may contain: 1) functions ; syntax ff(..); where ff is one of the following available functions : abs(x) absolute value of x sqrt(x) square root of x sin(x) sine of x asin(x) inverse sine of x cos(x) cosine of x acos(x) inverse cosine of x tan(x) tangent of x sec(x) secans of x csc(x) cosecans of x cot(x) cotangent of x atan(x) inverse tan of x atan2(x,y) ... Any operation on a BLANK causes the result to be set to BLANK (except the function IFBLANK). ...

... The file contains energy bound information and absorption coefficients used in the analytical model that constructs the response matrix. ... The energy bounds of PI channels (not used ?) Attributes: . None. Columns: . CHANNEL : . The PI channel number. E_MIN : . ... E_MAX : . ... The energy bounds of PHA channels (not used ?) ... The energy bounds of the PI channels, used to determine the equivalent energies of spectral channels in the redistribution matrix construction. ...

... Generate the list of ts les The rst thing to do is generate a le containing a list of the fits les you are interested in. ... You've de ned the in and out paths fitspath and mhpath, and the lename containing the list of ts les is called fitsfilelist. ... You generate all the lsfs les with lsfs_wrap, fitspath, mhpath, 'fitsfilelist', lsfspath Of course, if you're running IDL in a directory other than the one containing fitsfilelist, then you'll need to specify the path to fitsfilelist. ...

... This command selects one subframe from the original frame and generates an artificial image identical to the primitive but with the quoted window added at given positions. If this window contains one stellar image, one is able to determine, through a new ROMAFOT session, the ability of the procedure to detect an object and the general reproducibility of the photometry. A catalogue, similar to that created by FIND/ROMAFOT , is generated by ADDSTAR/ROMAFOT . ...
