Observation and Calibration Methods for the KFPA

Modification Request #9 (C04 2009)

---

1. Introduction

The KFPA Pipeline will monitor the GBT observing status and produce real-time data reduction and processing to produce GBT images of observer selected regions. The Pipeline will perform a limited set of data reduction techniques to produce a consistently calibrated image of the requested region.

The pipeline goal is to provide the astronomer with a completely calibrated, good quality image of the region of interest with minimum interaction from the observer. This will only work for observations executed in the manner specifically defined for each pipeline use case.

The goal for the output is that it should have all readily available calibrations applied to the data. The calibration should include atmospheric attenuation, elevation dependent gain corrections and the appropriate GBT efficiency calibration. The output units of the images will be in T_B* (Kelvin).

There are two major classes of observations that will be supported:

• Position switched, where the reference scan will be obtained from observations of specific location(s).
• Frequency switched, where the reference scan will be observed simultaneously with the mapping observation.
