This file is used to store processing state between calls to the level 0 to 1 software. Each time a level 0 file is received, the name of the file, the start time and the stop time in GPS seconds are noted in this file.

If a level 0 file spans two days, its record is put in the day's status file on which the file ends. For example, if a GPS/MET file runs from day 1997.033 to 1997.034, its record would be put in lev1St_1997.034_txt.

The file is in perl format, as read and written by the script State.pm. Here is an example:

$self = bless( {
                 '_stateFile' => '/pub/champ/level1a/lev1St/lev1St_2001.153_pl',
                 'dumpinfo' => [
                                 {
                                   'ndump' => 1,
                                   'starttime' => '675475200',
                                   'leoid' => 1,
                                   'filename' => 'chpLrl_2001.153.00.00.1440_rnx',
                                   'endtime' => '675561599'
                                 }
                               ]
               }, 'State' );

dumpinfo contains information on the level 0 file.
