SAVE_DATA_F
Save Data Flags
Bit 0 Save Raw Data flag
Bit 1 Do Not Save Product Data
Bit 2 Ionogram Data Reduction, when set then databins
with amplitudes ≤ MPA will be lost
Bit 3 Ionogram PGH (Precision Group Height) mode
Notes:
DCART has a global option that can override Save Raw Data
flag selection to produce no raw files or produce raw files for
all available programs.
Option ‘Do not Save Product Data’ is used for testing and
some cases when you do not need to save produced data

TOP_RANGE
Top Range of the search window for the strongest echo
Search window is used to select a subset of ranges (see
NRO) around the strongest echo (199 E-layer, 400 F-layer)
Presently this parameter is used only by Doppler processing
when creating Doppler/Drift data product.

BOT_RANGE
Bottom Range of the search window for the strongest
echo
Search window is used to select a subset of ranges (see
NRO) around the strongest echo (80 E-layer, 200 F-layer)
Presently this parameter is used only by Doppler processing
when creating Doppler/Drift data product.

NRO
Number of Ranges to Output
(reduced number of ranges selected around the strongest
echo on each frequency)
Presently this parameter is used only by Doppler processing
when creating Doppler/Drift data product.
Set this parameter to 0 if you want all ranges to be output

TX_ID
Transmitter ID
In support of oblique sounding and Tx surveillance modes
For oblique sounding experiments with other DPS transmit-
ters, TX_ID is 000XXX, where XXX is Station ID.
For not oblique sounding this field is equal to ‘ ‘ (6 space
characters).
000000 means UNKNOWN station
