SIDARCHIVE Search Help

Use the SIDARCHIVE search form to search the JWST I&T data archive by test Name, target name, instrument, etc. By submitting a search query, you can then mark data for retrieval from the search results page.

Retrieval Type
Package type; either "file" or "package". File refers to individual FITS files while package refers to a tar file of various data sets. The database table is comprised primarily of values extracted from either FITS keywords (file type) or a readme file (package type). Therefore some entries may only be defined for one or the other retrieval type.

Test Name
Title of test as specified in the test plan. Note an "*" can be used as a wildcard character in any string field. For example, the test name can be given a value nir* to find NIRCAM tests. Case is ignored.

Test Number
This is defined as the number of test as specified in test plan, however it is stored as a string and frequently has the same value as the test name.

Target Name
Target name as dertermined by FITSWriter although the tester is responsible for updating its value (not defined for packages). Default is usually "unknown".

Instrument
Identifier for instrument used to acquire test data.

Data Mode
Reference number used to specify ground data processing requirements for this data. Note values are stored as a string!

Dates
When specifying a date, you need to include a date and an optional time. If time is omitted then then midnight (00:00:00) is assumed. This means that a specification like "July 1 1994" will look for observations done on July 1 1994 00:00:00, not for observations done for the entire day July 1 1994. To search for observations for an entire day use the range option described below.

Note also that when entering a date with the month in numerical format, the American ordering is used; i.e., the first number is the month.

The date can have any of the following formats (the month name can be spelled out or abbreviated to three letters; case is not significant):

      Jul 15 1994
      Jul 1994 15
      15 Jul 1994
      1994 Jul 15
      1994 15 Jul
      7/15/1994  <--- Note order of month/day of month/year for numeric formats
      7-15-1994
      7.15.1994
    

If the day is omitted, the first day of the month is assumed. This means that a specification like "July 1994" will look for observations done on July 1 1994 00:00:00, not for observations done during July 1994. Note also that when entering a date with the month in numerical format, the American ordering is used; i.e., the first number is the month.

If a time is omitted, then midnight (00:00:00) is assumed. Otherwise, you can specify a time in any of these formats:

      14:30
      14:30:20
      14:30:20:999
      14:30:20.9
      4am
      4 PM
      04:30:20 AM
    
To search for observations before a given date, use <, and for observations after a given date, use >. For example,
      > Jul 15 1994
      < Jul 15 1994
    
You can use the .. operator to search on a range of dates:
     Jul 1 1994 .. Aug 1 1995
   
This operator is inclusive on the first date and exclusive on the second.

Finally, you can search on a list of dates or date ranges. For example,

     Jul 1 1994 .. Jul 3 1994,
     Dec 1 1995 .. Dec 6 1995
   
will search for observations done within either one of these date ranges.

 

Exposure Time
The total exposure times in seconds. Currently exposure time is the only numerical field in the SIDARCHIVE table. As such, you can use numerical operators in your query such as ">" , "<", or perform range searches using "..". For example, to find exposure times between 1 and 10 seconds, enter: "1 .. 10". To find exposures > 100 sec, enter "> 100".
