Identification
* Some lines are forced to be folded here. This star is classified as RM, a candidate of variable stars, by the PIXY system. After identification, the system makes it clear as a known variable star: The name of identified variable star is expressed in the syntax "type=name". Please read the Object types in identification database for more details about the type. At the end of the PXF file, the data of variable stars which are in the image area but were not detected are recorded as NR. The position (x,y) is also recorded.
* Some lines are forced to be folded here. You can stop recording data of such non-detected stars by setting -noNR option after -identify option.

[Identification Check List] HT UMA RM-00004 0.3" 0.1" |
The name of a variable star, the star's ID named by the PIXY system, the difference from the detected position, the difference from the position in the star catalog, are recorded in this order. When the positional difference is too large, the identification may be a mistake.
When the system could not separate close double stars, one detected star can have several counterparts in star catalog. Sometimes, several data are recorded in star catalog for one star.

* Some lines are forced to be folded here.
In these cases, several positional differences are recorded, for each data in star catalog.
MCG+08-22-008 RP-00002 45.0" 46.8" 36.5" |
In this example, the difference from the data at R.A. 11h48m56s.11, Decl. +48o40'53".3 is 46.8 arcsec, and the difference from the data at R.A. 11h48m56s.43, Decl. +48o40'28".3 is 36.5 arcsec.
The difference from the position in star catalog is not output for a star not recorded in star catalog (ND). The difference from the detected position is not output for a star not detected but recorded in star catalog (NC).
MCG+08-22-007 ND-00001 56.4" STM0895 NC-00003 0.1" |
The system identifies based on the positional error recorded in the identification database. Sometimes a variable star can be identified with several detected stars. The double-identified stars are recorded at the end. The name of such stars and the number of identified detected stars are output.
[Double Identifications] NGC 3928 2 NGC 3893 2 MCG+08-22-019 2 MCG+08-22-007 2 |
The data of such double-identified stars appear several times in [Identification Check List]. For example, the data of NGC 3928 appears twice as follows.
NGC 3928 PS-00047 73.9" 75.2" NGC 3928 RM-00002 4.4" 3.8" |
The positional difference implies that RM-00002 should be the right identification and PS-00047 should be a mistake.
Batch mode
Several PXF files can be identified at one time using a batch file containing names of all PXF files. After -identify option, set the -batch option and the name of batch file. For example, to identify with a batch file sample.bat, run the system as follows.
| java -Dmisao.home=C:\misao misao.pixy.Pixy -identify -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 save the verification result into a check file, write the name of check file in the same line.
sample01.pxf sample01.icl sample02.pxf sample02.icl sample03.pxf sample03.icl |
