Get a list of ProcedureComputation objects. ProcedureComputations have a 1:1 mapping with Observations where used.
These may have a number of 2 or more components made up of combinations of Computation and Acquisition records.
The details of the underlying records have been serialised.

### Available end points:

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

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

None
### How to use filters:

            "abstract": "This computation involved: deployed on European Remote Sensing satellite 2 (ERS-2).  European Remote Sensing satellite Two (ERS-2), successor and nearly identical to ERS-1. It follows the same orbit as ERS-1 and was launched in April 1995.\r\n\r\nERS-2 was nearly identical to ERS-1. The platform is based on the design developed for the French SPOT satellite. Payload electronics accommodated in a box-shaped housing on the platform; antennas fitted to a bearing structure. \r\nERS-2 carries the following instruments:\r\n\r\nAMI - active microwave instrument consisting of a synthetic aperture radar (SAR) and a wind scatterometer (both in the C-band). \r\nRA- radar altimeter: takes precise measurements of the distance from the ocean surface and of wave heights. \r\nATSR - along-track scanning radiometer (operating in the infra-red and visible ranges): measures sea surface temperatures and the vegetation cover of land surfaces. \r\nGOME - global ozone monitoring experiment, an absorption spectrometer which measures the presence of ozone, trace gases and aerosols in the stratosphere and troposphere. \r\nMS - microwave sounder: supplies data on atmospheric humidity. \r\nPRARE - precise range and range rate equipment: ERS orbit and trajectory determination. \r\nLRR - laser reflector: determines satellite position using ground-based laser stations. \r\nIDHT - instrument data handling and transmission: temporary on-board data storage by means of two 6.5 GBit tape recorders, equivalent to the data volume acquired in one orbit. Recording, formatting and transmission of data at 105 Mbit/s (transmission of SAR imaging data in real time), or 15 Mbit/s (transfer from tape recorder).\r\n\r\n",
