Description of contents:
    1. 1913.WeisbergHuang.in is the input file for the pulsar timing analysis program
    Tempo (also referred to here as tempo(1) so as to distinguish it from a separate
    program called tempo2. (See System requirements). It is used to produce the results in this paper.
   The time unit used in 1913.WeisbergHuang.in is Barycentric Dynamical Time (TDB).

    2. Fixed-format Time of Arrival(TOA) files.  The  files contain: 
    (1) fixed-format TOA lines; and 
    (2) interspersed tempo commands, as follows:
        SIGMA x     Set uncertainties of following TOAs to x us(SIGMA 0. means   using instead 
                    the  uncertainty listed in the TOA file)
        EFAC  x     Multiply uncertainties of following TOAs by x
        EQUAD x     Additional uncertainty in following TOAs in us, added in quadrature
        TIME  x     Add x (seconds) to following TOAs. The TIME command is cumulative, even 
		    across input files. On the other hand,  new SIGMA, EFAC and EQUAD commands override the
		    previous ones (while these commands still spill over across input
		    files). There are also several TIME flags in 1913.WeisbergHuang.in accounting for
		    instrumental/profle offsets. The SIGMA 0. command in 1913.WeisbergHuang.in before
		    1913.wappnew.1170.2003 reflects the use of TOA uncertainty starting from the WAPP data.
		    (Due to the structure of tempo, it was most straightforward to put certain TIME flags
		    in the .in driver file, while others are placed in the TOA files.)

    The TOA format (approximately the Princeton Format, but most importantly is that it is readable by tempo)
    is specified as follows:
        columns     item
        1-1     Observatory (one-character code)[3 throughout this dataset, =Arecibo]
        2-2     must be blank
        16-24   Observing frequency (MHz)
        25-44   TOA (in Modified Julian Date, decimal point must be in column 30 or column 31)
                   (The TOAs are refereced to the Arecibo observatory clock.)
        45-53   TOA uncertainty (microseconds)
        54-	generally includes calendar date and a variety of other information not used by tempo.

      The names of the TOA files are:
        1913.mk1.1colover.MJD
        1913.nmk2.MJD
        1913.nmk3.MJD

System requirements: All files are in human-readable ascii format. To conduct
timing analysis, Tempo,  appropriate 
clock correction files, and the datasets included here are needed. [See ref. 1 for 
tempo documentation and download instructions. Any
tempo version on the ref. 1 link, committed on 2016 Apr 7 or later should work.]

Additional comments: 
1, Note that this dataset will NOT work natively as input to 
program tempo2, due to subtle differences in tempo2's handling of flags and time
corrections and a different system of ephemeris time, among other issues.

2. This dataset has also been placed on http://zenodo.org/
