Phrase: Proportional Counter Array | Statement: [RXTE, instruments, Proportional Counter Array]

Target entity: Proportional Counter Array
Context triple: [RXTE, instruments, Proportional Counter Array]

• A. Anti-Coincidence System
  The Anti-Coincidence System is a detector subsystem used in gamma-ray astronomy instruments to identify and reject background charged particles, improving the accuracy of high-energy photon measurements.
• B. Silicon Drift Detector
  A Silicon Drift Detector is a type of semiconductor radiation detector that uses lateral electric fields to drift charge carriers to a small collecting anode, enabling high energy resolution and fast, low-noise signal readout in applications such as particle tracking and X-ray spectroscopy.
• C. Radiation Assessment Detector
  The Radiation Assessment Detector is a scientific instrument aboard NASA's Curiosity rover designed to measure and characterize the radiation environment on Mars and during the journey through space.
• D. Medipix2 readout chip
  The Medipix2 readout chip is a pixelated semiconductor detector ASIC developed at CERN that enables high-resolution, single-photon counting and energy-sensitive imaging for applications in particle physics, medical imaging, and material science.
• E. MPPC
  MPPC, short for the Motion Picture Patents Company, was an early 20th-century American film trust that sought to control the motion picture industry through patent pooling and licensing.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Proportional Counter Array
