| 284 | === Start up mosaic control software === |
| 285 | |
| 286 | On mayall-2 open a terminal window and: |
| 287 | {{{ |
| 288 | ssh -XY observer@mosaic3 |
| 289 | nocs start ccp |
| 290 | nocs start all |
| 291 | }}} |
| 292 | Once nocs is up and running, rearrange windows as desired, and check the status of the system by typing |
| 293 | the following in a nocs terminal window: |
| 294 | {{{ |
| 295 | nocs status all |
| 296 | nocs fullstatus ccp |
| 297 | }}} |
| 298 | Check that all is well by taking a test zero exposure. |

| 301 | === Take dome flats and zeros === |
| 302 | |
| 303 | During the afternoon (after 4pm), take dome flats with the telescope pointed at the white spot. [[BR]] |
| 304 | 1. Check that telescope is pointed to the white spot with mirror cover open [[BR]] |
| 305 | 2. Take 10 zero exposures [[BR]] |
| 306 | 3. Turn on low dome flat field lamps at 100% intensity (~50V) [[BR]] |
| 307 | 4. Create a dome flat script using the NGUI interface. Exposure times as follows: [[BR]] |
| 308 | z-band : 20 sec [[BR]] |
| 309 | r-band : 25 sec [[BR]] |
| 310 | g-band : 20 sec [[BR]] |
| 311 | Take 11 flats in z-band every night; only take flats in other bands if you intend to use them. Counts should be ~18-20k adu. |
| 312 | 5. Take 20 zero exposures [[BR]] |
| 313 | 6. Go eat dinner [[BR]] |
