NOTES:
[1] Unless a specific configuration sequence number is specified on he
col. 15, all measurements that include this station or this
satellite will be deleted (or selected).
[2] The station/satellite configuration number enables the user to
delete (or select) measurement types including more than one
station or more than one satellite without affecting other
configurations which may include the same station or the same
satellite.
Here are some examples:
In the case of measurement type 51 (two-way range) where only one
station and one satelliteare involved, the user does not need to
specify anything on col. 15 of the DELETE or the SELECT card.

----+----0----+----0----+----0----+----0----+----0----+----0----+----0----+----0
will delete all measurements 51 from all stations to satellite
# 7603901 between the times 830901 and 830903.

DELETE 314 517603901 830901 830903

will delete all measurements 51 from station 314 to satellite
# 7603901 between the times 830901 and 830903.
In the case of measurement type 61 (singly differenced one way
ranges where we have one satellite and two stations we will need
two DELETE (or SELECT) cards for precise specification of the
configuration ie.

This means, delete all measurement types 61 from configurations
where station 321 is the first station and 421 is the second
station in the configuration both observing satellite # 8003201.
Another example is given here for measurement type 87 (doubly

This setup will delete all observations of measurement type 87
with the following cofigurations:
1. stat 1 =321, stat 2= 421, sat 1= 8003201 and sat 2= 8307201
between times 870103 121956.000 and 870103 122156.000

(Cards 7 and 8)
An efficient way for the user to find out how many DELETE
(or SELECT) cards he/she needs for each measurement type is
to look at section 5.0 in Vol 3 of the GEODYN II documentation
(Measuremebnt types). The measurement type description indicates
how many stations and satellites are involved.
Assuming we have three stations and three satellites involved,
the way to find out which goes on configuration number 1, 2 or 3
is to look at the unit 90 output of TDF. Satellites and stations
under trhe label ONE, TWO or THREE correspond to the DELETE
(or SELECT) card configuration number.
It is important for these complicated measurement types to
specify information on as many DELETE (or SELECT) cards as
the maximum number of stations or satellites involved in the
measurement type.
IF CARD OMITTED: No data that has been selected will be deleted.
