SwiftUVOT Search Help

Use the SwiftUVOT Search form to search by object name, position, observation date, etc. and to specify the output format. You can then preview images and mark data for retrieval using this interface.

Filter
Filter used for exposures. Possible values include: B, BLOCKED, MAGNIFIER, U, UGRISM, UNKNOWN, UVM2, UVW1, UVW2, V, VGRISM, and WHITE

Observation Start Time
The date of the observation. More specifically, the date and time, in GMT, on which the first exposure was started.

When specifying this 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. Note this is the sum of all the exposures in the observation/filter set.

Observation ID
The Obs_id uniquely defines each observation. The first 8 characters are the same as the target ID. The last three characters indicate the observation.

Note that for each observation, several exposures may be taken using different filters.

Number of Exposures
The total number of exposures taken as part of the particular observation.
