h1. Using Guider and Navigation Plots

These are simple python tools for generating plots.

1. Log into DECamObserver@observer2.
9 1 Marc testing Mengel
2. cd annis/Navigation
10 1 Marc testing Mengel
2.5 bash
11 1 Marc testing Mengel
3. source ./Navigation
12 1 Marc testing Mengel
4. After the python window starts,:
13 4 James Annis
In [1]: plt.clf(); ihData.navigate()
14 1 Marc testing Mengel
15 1 Marc testing Mengel
In order to save a guider plot, hit the "floppy disk" icon
16 1 Marc testing Mengel
on the Figure 1 window with the navigation plot.

The navigation plot uses data from quick reduce. The
21 4 James Annis
green points are good Main Survey data.
22 1 Marc testing Mengel
if they are from a Main Survey program. The red dots are
23 4 James Annis
Main Survey data taken tonight. The letters are the SN fields. The contours are lines of constant
24 1 Marc testing Mengel
airmass. These are calculated for now; re-issuing the command
25 1 Marc testing Mengel
changes both the airmass and the data taken today.

27 1 Marc testing Mengel
The bottom right plot is the data rate plot.
28 1 Marc testing Mengel
On average the DES takes 150 images per night
29 1 Marc testing Mengel
in the Main Survey program. This number is just
30 1 Marc testing Mengel
2*5*5000sq-deg/105 nights,  divided by the tiling
31 1 Marc testing Mengel
area of the camera, pi sq-degrees. We don't have 
32 1 Marc testing Mengel
to do this every night: for example the SN fields don't
33 1 Marc testing Mengel
count. Over a week or two time scale we should average
34 1 Marc testing Mengel
150 images/night.

In [1]: plt.clf(); guider.plot(163529)
