Apparent places of fundamental stars for Computer Ephemeris for 2014 (DE200/LE200).

Computer Ephemeris for 2014 from DE200/LE200.

Apparent places of fundamental stars. Example.

Due to huge amount of data in this section of Computer Ephemeris, please, download zip file here.

Here you may see only example.

Information is arranged in little tables four stars each. The first row contains FK5 number, magnitude, spectral class, name of the star. We have FK5 stars 904, 1630, 905, 1001 in examlpe below. The second row contains date when upper culmination of star take place twice. Then alpha0 and delta0 follows. These numbers must consist of four digits. If there are no four digits, please add leading zeroes. In example for FK5 = 904 we have 21-Sep, alpha0 = 1 = 0001 = 00h01m and delta0 = -7704 = -77o44m. After two rows explained there is table of 39 rows. Each row contains approximate date of upper culmination, seconds of apparent right ascension, difference alpha of current row minus alpha of the previous row, seconds of declination, difference delta minus delta previous. To form apparent right ascension for the date of interest add seconds of apparent right ascension to alpha0. The same method is for apparend declination.

After all there are four lines. Line 'J1997.5' contains seconds of alpha and delta to be added to alpha0 delta0 to form mean place at J1997.5. The next lines contains secans and tangent of mean delta and reduction quantities a, a', b, b'.
