Execution
Registration of magnitude data estimated by the PIXY system into the magnitude database is run by -update option of the PIXY system, with a name of PXF file created by the PIXY system.
The magnitude database is constructed under obs directory under the MISAO home directory.
You must set the property misao.home as the MISAO home directory's path, using -D option of java command.
For example, let's register the magnitude data of the sample image in the Tutorial into the database.
The PXF file is sample2.pxf.
Here let's see the MISAO home directory as C:\misao.
Now type as follows and run the registration.
java -Dmisao.home=C:\misao misao.pixy.Pixy -update sample2.pxf
|
Result
It is not realistic to accumulate magnitude data of all detected stars.
So only magnitude data of significant stars are registered in the database.
Definitely, the stars satisfying one condition of the following two conditions are registered.
- A known variable star in the identification database, whose type is one of V, S, E.
- A remarkable star judged by the PIXY system, whose code is one of ND, NC.
The structure of the magnitude database is as follows.
obs/variable/AND/
obs/variable/APT/
obs/variable/APS/
:
obs/variable/NSV/
obs/variable/MisV/
:
obs/variable/others/
obs/suspicious/iras/
obs/suspicious/others/
obs/suspicious/misao/
obs/error/others/
|
The magnitude database is constructed under obs directory under the MISAO home directory.
Under the obs directory, the following three directories are created.
variable | Containing variable stars (the data in the identification database whose type is V) |
suspicious | Containing suspicious variable stars (the data in the identification database whose type is S), or remarkable stars judged by the PIXY system |
error | Containing catalog errors (the data in the identification database whose type is E) |
* Please read Reference Catalogs for more details about data in the identification database.
Under the variable directory, directories for all constellations, such directories as NSV, MisV, etc., and others directory are created.
The magnitude data of a star whose name contains the constellation name, such as R And, HT Cas, are saved under its constellation directory.
The data of NSV or new variable stars discovered in the MISAO Project, etc., are saved under such directories as NSV, MisV, etc.
Other variable stars are saved under others directory.
All data of one star is in one file.
Under the suspicious directory, the following three directories are created.
iras | Containing IRAS objects. |
others | Containing other suspicious variable stars. |
misao | Containing remarkable stars judged by the PIXY system, not identified with any data in the identification database. |
IRAS objects and remarkable objects of the PIXY system are classified in some blocks per 1 hour in R.A. and per 10 deg in Decl.
All stars in one block are saved in one same file.
For example, the file 13+20 contains all magnitude data of stars between 13h and 14h in R.A. and between +20 deg and +30 deg in Decl.
The file 22-30 contains all magnitude data of stars between 22h and 23h in R.A. and between -30 deg and -40 deg in Decl.
All data of one star is in one file in case of other suspicious variable star.
Under the error directory, others directory is created.
All magnitude data of catalog errors are saved in the directory.
All data of one catalog error is in one file.
When creating a new magnitude database and registering only the sample PXF file (sample2.pxf) into the database, the result becomes as follows.
Example of magnitude database
The list of image information is also created under the MISAO home directory.
It contains the [Image Information] in the PXF file registered into the magnitude database.
The image information list created after registering only the sample image is here.
image_information.list
The image information list is used in the New Object Survey.
Format
When a file contains magnitude data of only one star, only magnitude data are recorded.

* Some lines are forced to be folded here.
The name of remarkable stars of the PIXY system is based on the R.A., Decl. and the positional error.
The name is automatically modified when a more accurate position of the star is obtained.

The two stars' names in this example mean as follow.
Name | R.A. | Decl. | Positional error |
J040709.09+440338.9-73.3 | 04h07m09s.09 | +44o03'38".9 | 73.3" |
J044743.40+451125.6-5.0 | 04h47m43s.40 | +45o11'25."6 | 5.0" |
The positional error here is three times of the positional error output by the PIXY system.
But when the star has a counterpart data in star catalog, or when the positional error becomes smaller than 5.0 arcsec, the system records the error as 5.0 arcsec.
Image name change
The image name recorded in the magnitude database is that recorded in the PXF file.
If you would like to change it, set -image option after -update option.
For example, to register the result of the sample image with the image name "example", run the system as follows.
java -Dmisao.home=C:\misao misao.pixy.Pixy -update sample2.pxf -image example
|
Batch mode
Several PXF files can be registered into the magnitude database at one time using a batch file containing names of all PXF files.
After -update option, set the -batch option and the name of batch file.
For example, to register with a batch file sample.bat, run the system as follows.
java -Dmisao.home=C:\misao misao.pixy.Pixy -update -batch sample.bat
|
In the batch file, write one name of PXF file in one line.
sample01.pxf
sample02.pxf
sample03.pxf
|
If you would like to change the image name, write the new image name in the same line.
sample01.pxf sample01
sample02.pxf sample02
sample03.pxf sample03
