A1763: xband h₂o maser search

---

Intro:

1. compute on/off -1 by record
2. For each freq channel do a linear fit along the time direction throwing out any points that are outliers (fit residuals greater than 3 sigma). Iterate the fit till no more points are thrown out. Average the results keeping track of the number of seconds of integration for each channel.

The plots

• Top: the grand average (time and polarization) with the baseline removed. Units are Tsys. The quoted rms is for the points that were used in the baseline fit.
• Middle: The time averaged data before base lining and before combining polA (black)  and polB (red). The units are Kelvins.
• Bottom: For each pattern (before averaging) the rms/mean along the time direction is plotted. This values should only depend on the integration time and channel width.  Channels that have rfi usually have larger rms's because of the time variability. Since we have divided by the mean, the units are Tsys. Black is polA, red is polB..
