7.3 LST Clock (is currently unavailable)

    You can check Local Sidereal Time (LST) at NRO.

Fig 7.1  LST Clock

7.4 Mult PA

    You can make a LST-EL (elevation angle) diagram of sources which are defined in Source Table. You can also check the rotation angle (PA) of the rotator of a multi-beam receiver.

Fig 7.2  Mult PA

1. Push File list button.
2. Select tables for LST-EL diagram. For LST-PA diagram, select a table from the file list and enter a position angle of the multi-beam receiver edfined in Device Table.
3. Push Draw button.

*If you enter source position of Source Table up to six decimal place, LST-EL diagram may not be plotted correctly.

7.5 Point Log

    You can search the past pointing log. This tool is useful to check the intensity of pointing sources before your observations.

Fig 7.3  Point Log

1. Enter source name in SOURCE. You can use the SiO maser list to search a source that is close to your target.
2. Push SEARCH button. The peak temperatures of v=1 and v=2 lines are shown in the log, if there are records.

*If you record the intensity of the pointing source you observed, it is useful for other observers. So, please don't forget to record it during your observations.

7.6 Obs Log

You can search the past observation log.

Fig 7.4  Obs Log

1. Enter any parameters. Refer the format in fig 7.4 for DATE and GRP.PRJ.
2. Push SEARCH button.

7.7 Obs Point

You can check the location of ON positions and scan number of each ON position.

Fig 7.5  Obs Point

1. Select Observe Table from File List.
2. Push Plot button. The plot window appears as shown in fig 7.6.
3. Push left mouse-button to check total number of scan, n, at each point. n is shown in the bottom right corner of the plot window. The points with the same color have the same scan number.
4. Push right mouse-button in the plotted window to finish.

* Channel of a multi-beam receiver can be specified by Channel button.
* Points within Radius are regarded as the same position.

7.8 Schedule

You can make a list of Observe Table for batch mode.

1. Select Observe Table from the list.
2. Enter file name and push Make button. A file of the list is made and sent to the workstation that controls the 45-m telescope system.
