Page History

The Info view is used for two purposes; display the progress of an image exposure and set certain exposure/image related parameters in LOIS.

Image Modified

LOIS parameters

...

• Observer Info
  • Names
  • Affiliations
• Image Info
  • File Path; default value from config file
  • Root File Name; default value from config file
  • Initial Image Number; defaults to 1
  • Directory Path Date Extension; default value from config file
  • FITS Extension; default value from config file
  • Image Number Separator; default value from config file

Pressing the "Apply" button sends the commands to Lois to set Observer Info and the Image Info. Check LOIS Log to see if the commands were successful. You can Change Observer or Path information independently. Generally, one only needs to set the Observer information. The path information should be correct based on the values set in the config file for each instrument. The image path and name is displayed in the title of the collapsible widget. If any of the parameters for the image need to be modified, use the chevron to expand the section. The changes will be displayed in the title bar in real time but will not take affect on LOIS till the "Apply" button is used.

Observer Info

The names and affiliation of the observers should be set in this section. If Either of the two AREAS is blank it will remain as it was in LOIS's cache and most likely be incorrect. These parameters will be inserted in the FITS headers and are subjected to the same restrictions as all FITS headers; <= 72 characters.

Image Info

The widget for image information is pre-filled for each instrument based on the relevant values in the MasterInstrumentConfiguration.xml. For instance for LMI the section looks like:

    <storage-config>
      <path></path>
      <telescope-id></telescope-id>
      <instrument-id>lmi</instrument-id>
      <filename-abbr>lmi</filename-abbr>
      <root-filename-date>false</root-filename-date>
      <date-noon-rule>true</date-noon-rule>
      <dash-number>off</dash-number>
    </storage-config>

with the following result:
