| + | - Start with an M10 alignment before beginning the coude process (usually done on POP 5) | ||
| + | - Send M7's to default | ||
| + | - Do regular beginning of the night alignment procedure | ||
| + | - align beacon, dichroic, focus labao, focus wfs | ||
| + | - Open an engineering hut GUI: >> hutgtk -E S1 & | ||
| + | - AOB ENG tab | ||
| + | - note the M7_1 and M7_2 actuator positions and enter them on the Excel page. | ||
| + | - Select and hit **[GET].** | ||
| + | - Value reads below get and should match last entry on excel | ||
| + | - Turn powers on and enable scope(s) | ||
| + | - Dome GUI, Auto tab: | ||
| + | - On 'Az Pos', enter the stow position + 180 | ||
| + | - **[Set Pos]** | ||
| + | - Watch beacon spots and use M7 to keep them centered while it rotates 180°. | ||
| + | - Obsgtk, align M7 when it stops moving. | ||
| + | - Hut GUI, note new M7_1 and M_2 values and enter in excel. | ||
| + | - ignore last 3 digits and record first 4 | ||
| + | - spreadsheet will calculate the average value | ||
| + | - enter the average value + 3 zeros for each actuator (M7_1 and M7_2). | ||
| + | - If its a large move, watch the beacon spots as they move away because you will need to recenter them | ||
| + | - Use the dichroic to realign the beacon to labao | ||
| + | - Hit **[STOW]** | ||
| + | - The beacon movement should be much smaller returning to stow than it was going away from stow | ||
| + | - Align M7 | ||
| + | - Enter new actuator positions into excel | ||
| + | - Hut GUI, send both actuators to calculated position. | ||
| + | - Align dichroic | ||
| + | - if the beacon movements were small on the way back to stow, then the coude alignment is finished. If it wasn' | ||
| + | - Hut GUI, save the new M7 dichroic positions by hitting **[DICHR POS] **then **[WRITE CFG]** | ||
| + | - it will save them to / | ||
| + | - Can enter any notes on why coude alignment was needed on excel sheet. | ||
