The possible types of cycle slip flags are the following:<br />

6.5 Preprocessing Phase Observations<br />

DUA means that the cycle slip was found by the dual band algorithm using the conditions<br />

(6.6) and (6.8),<br />

SNG means that the cycle slip was found by the single frequency algorithm using the<br />

condition (6.8) only,<br />

CLK indicates a so-called clock jump (jumps on the single-difference level, see Section 6.5.3),<br />

and<br />

JMP indicates a clock event: A ms-jump has been corrected (only when preprocessing zerodifference<br />

files).<br />

The items which were changed in the most recent run are marked by an asterisk in the<br />

column “N”. A long list of the pieces of measurements marked or changed follows:<br />

The possible marking types are:<br />

DUA dual band algorithm, see Section 6.5.3,<br />

SNG single band algorithm, see Section 6.5.3,<br />

USR defined in the “Satellite problems” file (description in Section 6.7.2 and 22.4.6), or<br />

no valid position for an epoch in the “Kinematic input coordinates” file (other than flag K)<br />

if the “Kinematic coordinate estimation” is disabled, see Section 6.5.5,<br />

UNP marked epochs with unpaired observations (L1 without L2 or vice versa),<br />

ELV observations at low elevation,<br />
