** Preparations [#bf653982]
+ Login to COSMOS3 manager GUI with Group=''asteXX'' (e.g. aste16) and Project=''sbref''
+ Tune the receiver to be used
+ Check Aspirin is in the ''WIND ON'' mode
-- Aspirin status can be confirmed by looking at the Aspirin Monitor window.  Check the following three items.
 Current time = 2016/09/02 08:22:15    <--- The differences among these three times
 Aspirin time = 2016/09/02 08:22:14    <--- should be less than 60 seconds.
 Weather time = 2016/09/02 08:22:08    <---
 Aspirin Offset : (Az, El) = (   6.64,   0.42 )
 Aspirin status : ** WIND ON ** ( C22:on  C6:OFF WIND:on )    <--- should be "WIND_ON"
 Refraction Corr. status : OK                                 <--- should be "OK"
+ Launch ''CONT qlook (qlookc)'' from cos3launcher
-- Push the ''START'' button

** Measurement [#ld2b04de]
+ Adjust pointing using either of the following observation tables (preferable, but can skip)
#br
|CENTER: Planet|CENTER: Receiver|CENTER: Obs. file|h
|Jupiter|DASH345|jpx5d3.start|
|~|BAND8|jpx5b8.start|
|Saturn|DASH345|stx5d3.start|
|~|BAND8|stx5b8.start|
#br
-- Pointing errors like a few arcseconds can be ignored, because mapping area is large enough to cover the planets
-- Auto-pointing is available toward bright planets
-- Turn on auto-pointing on the CONT qlook if necessary
+ Measure z-position of the sub-reflector by running either of the following observation tables
#br
|CENTER: Planet|CENTER: Receiver|CENTER: Obs. file|h
|Jupiter|DASH345|jpsbd3z.start|
|~|BAND8|jpsbb8z.start|
|Saturn|DASH345|stsbd3z.start|
|~|BAND8|stsbb8z.start|
#br
-- if ''|dz| > 0.1 mm'', add its resultant offset to dz.
-- The additional offset in z-axis might slight pointing offsets. However, this can be ignored because of mapping observations.
+ Run either of the following observation tables according to a planet and a receiver [#t513e168]

** Analysis [#za235565]
+ Login to an analysis computer (e.g. aste-ms1/aste-mx3) with account=''asteXX'' (e.g. aste16)
+ Rsync CONT data from the ASTE site
 asteXX@aste-ms1: ~/analysis/bin/cont_rsync.sh <project> <obs. table> <time> -link
 e.g.)
 asteXX@aste-ms1: ~/analysis/bin/cont_rsync.sh sbrf16 str02b8 2016-08-15 -link
 ...
-- cont_rsync.sh ''-link'' automatically create symbolic links with old file names to new CONT files
-- The symbolic links can be also created by cont_link.sh, if you miss to put the ''-link'' option
 asteXX@aste-ms1> ~/analysis/bin/cont_link.sh ~/sbrfXX/continuum/data/CONT.*.LCK
+ Run ''cont''
 asteXX@aste-ms1> ~/analysis/bin/cont.sh
++ Map Analysis>CFITS
+++ Select a LCK file in the ''.LCK File List'' button
+++ Set parameters~
Normally, it is enough to use default values as shown below.
&br;
&ref(cfits_v6.png,,75%);
+++ Push the ''EXEC'' button to create a image FITS file
++ Map Analysis>CMAP
+++ Select the image FITS file created in the previous step
-- &COLOR(RED){Endian conversion is UNNECESSARY for continuum data taken on Linux COSMOS3.};
-- ''LCK endian'' and ''FITS endian'' buttons are NOT available.
+ Read the exported FITS on ''ds9'' for further processing
 asteXX@aste-ms1> ~/analysis/bin/ds9_bmap.sh <FITS>
