ED
End of Day
At the end of each solar day (solar midnight) it is desirable to summarise, sort, and print out
the results of the tests and observations taken the previous day. This may be achieved by
using the ED command.
The ED routine:
•
summarises data into an “S” file (see SUM).
•
sorts and prints data from observations and tests (see OZSUM, FMSUM, FZSUM,
HGSUM, SLSUM, UVSUM, ZSSUM).
•
prints constants and monitored values (see PO, AP).
•
executes a series of tests (see HG, SL, DT, RS, SR, RE, FR)
The first command in ED is a print command, which directs the printout to the printer (see
PN) or to a disk file (see PD). If the operator wishes to change the printing path, either the
ED-PD.RTN or ED-PN.RTN must be copied to ED.RTN.
An operator may run ED at any time. If the Brewer is running in a schedule (see SKC), the
ED command is initiated automatically at solar midnight.
See also ED-PD and ED-PN.
ED-PD End of Day, print to disk
ED-PD and ED-PN are the same as the ED command but the operator may easily select the
method of printout. In the Brewer program directory, either the ED-PD.RTN or the ED-
PN.RTN may be copied to the ED.RTN, resulting in the ED printout being directed to a disk
file or to the line printer (see PD and PN commands). See also ED, ED-PN commands.
ED-PN End of Day, print to printer
See ED, ED-PD commands.
END_DAY End of Day (past day)
Command Syntax: END_DAY Feb29/98 or END_DAY 06098
END_Day performs an End of Day on a previous day’s data. For the command syntax
example: if the raw data file B06098.nnn exists, a Summary file (S06098.nnn) will be created
and summary files printed.
FF
Form Feed
FF results in a Form Feed on the printer.
FM
Focused Moon Observation
FM results in an O
3
observation to be taken with the moon as the radiation source.
The Brewer Zenith Prism and Azimuth Tracker are oriented to the moon, the Iris is opened,
FW#1 is rotated to the position 3, and FW#2 is adjusted for maximum intensity, starting at
position 2.
Data is recorded on disk and is printed as previously determined by PN, PD, and PF
commands. An FM observation consists of five sets of 80 cycles of the slit mask (a
measurement), each cycle taking a reading for 2*0.14 seconds on each wavelength. Intensity
data for six wavelengths, and the dark count, from the five measurements is recorded. The
Azimuth and Zenith positions are updated after each measurement.
After each measurement O
3
is calculated, and after the final measurement all data is
processed, resulting in a single summary set for the total observation.
In the NO
2
mode, a measurement of NO
2
is taken.
An FM measurement takes approximately 15 minutes to complete. Note that FM
observations are not valid for ZA>75° and the message ”Waiting for the Moon to Rise above
ZA=75° “ may appear prior to this angle condition being met. See also Appendix A .
