7================================================================================ CONTENTS OF THE DIRECTORY This directory contains the observational data of the mutual events of the Galilean satellites of Jupiter occurring in 1997. One will find: 1) - The file phemu97_ftp.dat (one line for each observation) This is a sequential ascii file with a recordsize of 91 bytes wih a following format, - the date of the minimum of the light curve in UTC (year,month,day,hour,minute,second) I4,5I2, - the code of event A4, - the error on the date of the minimum in seconds A6, - the magnitude drop in magnitude unit F7.3, - the error on the magnitude in magnitude unit F5.3, - the C-O in seconds from the ephemerides G-5 I5, - the observational site A8, - the code of the instrument L, T ou X A1, - the aperture in centimeter I3, - the code of receptor A6, - the filter used A5, - the integration time in seconds A5, - the size of the diagragm when used A5, - 5x, - the distance to Jupiter in jovian radii F5.1, - the elevation of Jupiter in degrees I3, - the elevation of the Sun in degrees I3, - the codes for the observational conditions I1, Code of event: in the format, xMyC, as, - x, occulting or eclipsing satellite - M, type of event O, for Occult E, for Eclipses - y, occulted or eclipsed satellite - C, Category of event, P, Partial event T, Total event A, Annular event B, eclipse by penumBra Code of the observers: cf. reference paper Code of the instrument: L, refractor T, reflector X, unknown Code of receptor: cf. reference paper Code for the observational conditions 0 = unknown conditions 1 = very good observational conditions 2 = acceptable observational conditions 3 = difficult observational conditions 2) - The photometric lightcurves as ascii files with one line for each photometric point Contents: - 282 observations of 98 events observed from 55 sites from june 1996 until november 1997 - each light curve corresponding to each observation, - the light curves are provided in the files dXXXYYY.ZZZ where XXX is the coded name of the site of observation on 3 characters, YYY is the type of phenomena, aammjj,ZZZ is the date. Example: dbor1e2.077 is Bordeaux(bor), 1e2 is J1 eclipse J2 and 077 Is July 7th - the file dXXXYYY.ZZZ.png provides the plot of the light curve Format: The lightcurves are provided in the files d.... with the following format, - first line : event, date, site of observation, number of points - second line: alpha, delta of jupiter at 0h, the julian data at 0h and a parameter to indicate we are in magnitue alpha is counted in hours and decimal fraction delta is counted in RADIANS - third line : longitude and latitude de of the observatory, the longitude is counted in hours and decimal fraction counted positively towards WEST (format F10.6), the latitude is counted in RADIANS counted positively towards north (format F9.7) - fourth line: KA,KX and sequante Z (KA and KX not used, sequante Z: inverse of cosine (zenithal distance) ) - line 5 and next: hour minute second in UTC, magnitude drop (the last column [.00000] is not used) 3) - the tables and figures of the paper describing the observations and published in Astronomy and Astrophysics: - zcatal97.tab4p1 to p9 .ps: tables 4 of the paper - zfich1 to 33 .ps: figures 1 to 33 of the paper ==============================================================================
