NAME
    aetimecalc -- Mission Time Calculator for Suzaku (Astro-E2)

USAGE
    aetimecalc input [mission/date/date_tt/mjd/mjd_tt/yday]
	
DESCRIPTION

    This task read several types of input time values, and calculates
    mission time (s), date string in yyyy-mm-ddThh:mm:ss.sss in UTC or TT,
    Modified Julian Date (dy) in UTC or TT, and the days from the launch.
    The result is written both to the screen and into the parameter file.
    This task takes leap seconds after January 1970 into account.
    The second parameter depends on the option chosen for the first 
    input parameter (see below). 

PARAMETERS

input [string]
    Any of prompt/mission/date/date_tt/mjd/mjd_tt/yday

mission [real]
    Mission time, i.e. accumulative seconds from date0,
    only required when input="mission".

date [string]
    Date string in UTC, 'yyyy-mm-ddThh:mm:ss.sss',
    only required when input="date".

Date_tt [string]
    Date string in TT, 'yyyy-mm-ddThh:mm:ss.sss',
    only required when input="date_tt".

mjd [real]
    Modified Julian Date in UTC (MJD-UTC), only required when input="mjd".

mjd_tt [real]
    Modified Julian Date in TT (MJD-TT), only required when input="mjd_tt".

yday [real]
    Days from the Y0 (launch date), only required when input="yday".

(leapfile = CALDB;$ENV{LHEA_DATA}/leapsec.fits) [file name]
    Name of the leap second file. The default value is set to
    indicate that aetimecalc will search for the file in CALDB first
    and then in the LHEA_DATA directory if necessary (the actual path
    for the HEADAS installation in use will be shown).

(date0 = "2000-01-01T00:00:00.000") [string]
    Reference date of mission time in UTC.

(yday0 = "2005-07-06T12:00:00.000") [string]
    Date string for Y0 (launch date) in UTC.

(mjdrefi = 51544) [integer]
    Integer part of the MJD-TT reference (2000.0 UTC).

(mjdreff = 0.00074287037037037) [real]
    Fractional part of the MJD-TT reference (64.184 s).

(anl_verbose = 0) [integer]
    ANL verbose level (-1:full, 0:minimum)

(anl_profile = no) [integer]
    Enable ANL module profiling

(num_event = -1) [integer]
    number of event (-1=all,0=exit)

(event_freq = 1000) [integer]
    Event number printout frequency

(chatter = 2) [integer]
    message chatter level (0:min,2:norm,5:max)
