Byte 0 - 10: File header identifier, ASCII: 'CAMRAS SETI'
Byte 11: Useless separator, ' '
Byte 12 - 15: Header version number ASCII, currently 'v0.1'
Byte 16 - 23: Time of first sample: make this a 64 bit number of
integer
seconds since the Unix epoch (8 bytes). Recordings start on integer
seconds.
Byte 24- 27: Right Ascension, 32 bit floating point number in IEEE-754
single precision format, in radians.
Byte 28 - 31: Declination, 32 bit floating point number in IEEE-754
single precision format, in radians.
Byte 32 - 39: Recording center Frequency in Hz: double precision
floating point number, IEE-754.
Byte 40 - 43: Sample Rate, in Hz. uin32_t format. We only support
integer sample rates in Hz.
Byte 44: Bits per sample: uint8_t (currently 1)
Byte 45: Recording format, 1 char. 'I' for interleaved IQ, 'R' for
real
samples. Should normally be an 'I'.
Byte 46: Polarization, 1 char, 'L', 'R', 'H' or 'V'
Byte 47: Antenna number, uint8_t (Currently: L-band = 1, UHF = 2, 0 =
undefined)
Byte 48: Beam number, uint8_t (usually 0)
Byte 49 - 1023: ASCII text for remarks, room for expansion in future
header versions.
