Hello all,

I've started to read SAC2000. There are some explain to header of SAC in
website:
http://www.llnl.gov/sac/
Which I did not understand.
I have an file SAC for example:
2002.185.16.01.21.5363.G.ECH.00.VHE.D.SAC
when I've seen the header this file : NPTS = 10547
B = 3.310000e-04 : Is it time begining at 16:01:21.536 or
not ?
E = 1.054600e+05
IFTYPE = TIME SERIES FILE
LEVEN = TRUE
DELTA = 1.000000e+01
IDEP = UNKNOWN
DEPMIN = -1.102900e+04
DEPMAX = -6.488000e+03
DEPMEN = -7.802379e+03
KZDATE = JUL 04 (185), 2002
KZTIME = 16:01:21.536 : What does it mean ?
KSTNM = ECH
CMPAZ = 9.000000e+01
CMPINC = 9.000000e+01
STLA = 4.821600e+01
STLO = 7.158000e+00
STEL = 5.800000e+02
STDP = 2.500000e+02
KHOLE = 00
LOVROK = TRUE
NVHDR = 6
SCALE = 4.210470e+09 : *What is this term ?*
NORID = 0
NEVID = 0
LPSPOL = FALSE
LCALDA = TRUE
KCMPNM = VHE
KNETWK = G


if I want to have this data from 00h00m00sto 23h59m59s of this day. How
can I do ?
