Each field can be searched using basic regular expressions. There are 12 metacharacters in regular expressions: $, (, ), *, +, ., ?, [, \, ^, {, and |. To match these characters literally, you must escape them with a backslash (\).

For example, the regex: $ \( \) \* \+ \. \? \[ \ \^ \{ \| matches the text: $ ( ) * + . ? [ \ ^ { |.

Observation Start Date

This field searches for the observation start date.

The date format should be in the format of 4-digit year, 2-digit month, and 2-digit day (yyyy-mm-dd).

• Input: 2015 matches records starting in 2015.
• Input: 2015-01 matches observations in January 2015.
• Input: 03 matches records where the start date includes "03".
• Input: 2015-06-10 matches data observed on June 10, 2015.
• Input: (2015-01)|(2016-01) matches observations in January 2015 or January 2016.

Experiment Code

The input string in the experiment code field can be searched as a substring.

Target Source Name or Coordinate Value

The target source name refers to the object being observed. Input strings for the target source name can be searched as substrings.

If the string includes the + character, prepend it with a backslash (\).

Example: To search for 0218+357, input 0218\+357.

Alternatively, you can search using the coordinates for right ascension and declination:

• Right ascension example: 12h30m31.0059000s
• Declination example: 35d58'29.504510"

You can also search for substrings of right ascension and declination:

• Right ascension example: 12h30m
• Declination example: 35d58'

Polarization, Band

If unchecked, the entire dataset is searched. If checked, the search applies an 'or' condition.
