Get a list of Instrument objects. Instruments have a 1:1 mapping with Observations.

### Available end points:

- `/instruments/` - Will list all Instruments in the database
- `/instruments.json` - Will return all Instruments in json format
- `/instruments/<object_id>/` - Returns Instruments object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `title`
- `uuid`
- `keywords`
- `instrumentType`

### How to use filters:

- `/instruments/?title__startwith!=Instrument.title: DETAILS NEEDED`
- `/instruments/?uuid=c7fa005e2095425392b18adbd7b40617`
- `/instruments.json?instrumentType=radiometer`

    "abstract": "The spectral radiometer provides a direct measurement of solar actinic UV flux and determination of photolysis frequencies. The actinic flux is measured between 280 - 650 nm (<1 nm resolution) using a spectral radiometer (Ocean Optics QE5000) attached to a quartz receiver optic (Metcon). Photolysis rates are derived from the product of absorption cross-section of the precursor molecule, the quantum yield of the photo-product and the actinic flux density (cm-2s-1nm-1).",
