The data file uses the naming convention DBID + dt.dat where DBID is a database identification name or string. The most common DBID's are:
The orbit file uses the naming convention DBID + or.dat
The header file uses the naming convention DBID + hd.dat

line 1 is the start and stop times of the database.
line 2 is the mergedb version number.
line 3 signals the end of descriptive information. The user can put additional comments after line 2 but before this line if necessary.
line 4 is the total number of stations.
line 5 is the total number of satellites.
lines 7-32 (in this case) are the satellite PRN numbers in no particular order.
line 34 is the station name, the station four character ID and the L1 and L2 half integer flags. A half integer flag value of "1" means only whole cycle slips can occur; a value of "2" means half cycle slips are possible.
line 35 station coordintes in meters.
line 36-38 is the surface temperature, pressure and relative humidity in degrees Celsius, millibar and percentage of saturation respectively.
line 39 is the north, east and up offsets, in meters, of the L1 phase center from a convenient or required reference point. These values are followed by the L1 - L2 up offset, also in meters, and the antenna type identifier.
The station block (lines 34-39) is repeated for all other sites.
