Observing Plan¶
- DES Half night
- Evening standards
prompt> standards 00:37 UT Date = '2019/01/09 00:37' Local time = 21:37 SDSSJ0000-0000 ra 00:00:00 dec +00:00:00 secz 1.7 SDSSJ0100-0000 ra 01:00:00 dec +00:00:00 secz 1.4 SDSSJ0320-0000 ra 03:20:00 dec +00:00:00 secz 1.2
- If seeing is better than 1.4 arcsec:
- Start with Alhambra Deep 2 in z, i.
- At 2:45 UT (~ 1.5 airmasses), clear any remaining exposures and do: MACSJ0416_z_2.json
- When that finishes, load the "redo" script: Jan07_redo_3.json (SISPI will probably skip a bunch of exposures if this is started after 3:00 UT)
- If the seeing is is worse than 1.4 arcsec for more than a few exposures
- Stop Alhambra/MACSJ sequence, clear queue and run obstac if it is before 3:00 UT.
- At (or after) 3:00 UT, run the redo script: Jan07_redo_3.json
- scripts are located at /usr/remote/user/DECamObserver/ExposureScripts/DES_scripts/
- Midpoint standards
