This is the scale factor as a code which could be either 0 or 1:
 0 = scale factor for pseudo range correction is better
than 0.02 meter and for range rate correction is 0.002
meter/second
 1 = scale factor for pseudo range correction is better
than 0.32 meter and for range rate correction is 0.032
meter/second
PRC is the Pseudo Range Correction as observed on the L1
pseudo-range at the reference station
This is the rate of change, in meters, of the pseudo-range
corrections
User Differential Range Error. An estimate of the performance
of the satellites pseudo-range as measured at the reference
station in meters. This number is provided as part of the
RTCM Type 1 messages in the form of a binary code 0 to 3:
0: ≤ 1 meter at 1 sigma
1: > 1 meter and ≤ 4 meter at 1 sigma
2: > 4 meter and ≤ 8 meter at 1 sigma
3: > 8 meter at 1 sigma
Data Ephemeris identifies the set of ephemeris parameters.
Gives the user a means of detecting change
The PPP Ref position table displays the GPS week, day and time and the geographical
WGS84 coordinates for the Apex or Ultra solution.
The table also includes the height above the Geoid model selected by the user in
Config/Calculation/Settings and the separation value from this Geoid model.
The column to the right shows the standard deviation of the individual coordinate
components.
The rows underneath show the latency of the last received Apex / Ultra corrections, the
Unit variance, Semi-Major and PDOP of the calculated PPP Position and its calculation
mode.
