| | 5 | We want a simple PGPLOT-based utility to |
| | 6 | * display UV data from a single baseline, in the format |
| | 7 | * channel number on X axis |
| | 8 | * time on Y axis |
| | 9 | * amplitude or phase shown as "greyscale" |
| | 10 | * display a cursor with 'live' readback of the amplitude/phase, channel number, frequency and timestamp |
| | 11 | |
| | 12 | We want to use this to select subsets of the displayed data and apply flagging commands to the subset. |
| | 13 | |
| | 14 | Display characteristics: |
| | 15 | * display one baseline at a time |
| | 16 | * we want to be able to jump to a different baseline number (forward and back thro' the sequence) |
| | 17 | * don't average time steps by default (make the averaging a command parameter) |
| | 18 | * do sum the channels such that the entire bandpass fits in the PGPLOT display window (allow turning this off via command line params) |
| | 19 | * if the uvdata array extends beyond the edges of the display window, allow scrolling (vertically or horizontally) |
| | 20 | * when it is possible to scroll, show an arrow (outside the display grid) (with the shortcut key letter shown as well ?) |
| | 21 | * arrow keys are the most obvious shortcut key! |
