! Define datum
! Datum Name; Semi-Major Axis; 1.0 / Flattening
_DATUM; NAD 83; 6378137.000000; 298.257222101


! Define the Units used in this file
! M - meters, U - US Feet, I - International Feet, C - Chains
! D - DMS, DD - Decimal Degrees, G - Grads (Gons), 
! Note: Lat and Lon must always be in DMS format (e.g., 100-30-40.1234 is entered as 100.30401234)
_UNITS; M; D




! Station to be fixed in Grid North and East
_LAT_NORTH_FIX;   AJAX
_LON_EAST_FIX;    AJAX




! _ADJUST_ keywords
! Keywords starting with _ADJUST_ are used in the Adjust From File option; they are ignored during Import.

! Indicates the type of adjustment (2D Grid or State Plane)
_ADJUST_2D_GRID


! Define if unknown stations (referenced by observations) should be created at Adjust Time.
! Unknown stations are those not defined in the _STA_COORD record (see below).
_ADJUST_CREATE_MISSING_STATION


! Mean height for 2D project
_ADJUST_MEAN_2DHGT; 3310.0


! Grid Zone (see list of all grid zones on our web site)
_ADJUST_GRID;  COLORADO,N,0501,L2
! Another way to define the zone (if you have the parameters) is shown below (use linear units defined above)
