DESCRIPTION OF CANOPUS CALIBRATIONS (at Eros) CanopusCal_1a (99-103) - The purpose of this canopus calibration, and all those that follow is to measure the point spread function of the material deposited on the lense during the Rendezvous 1 Burn anomaly. Observation design: Slew to put Canopus at center of msi fov. For each of the following filters (1,2,3,4,5,6,7,0), take 16 images through the same filter while slewing Canopus across a 2x2 pixel diagonal over 112 sec. The scan is reversed and continues for another 112 sec, bringing Canopus back to original position before repeat begins with new filter. Manual exposure values are 600, 999, 979, 999, 887, 999, 999, 70 ms, for each different filter respectively. CanopusCal_1b - (99-105) Slew to put Canopus at center of msi fov. For each of these filters (1,2,3,6), take 16 images through the same filter while slewing Canopus across a 2x2 pixel diagonal. Exposure values 600, 999, 979, 999 ms, respectively. CanopusCal_1c - (99-133) Slew to put Canopus at center of msi fov. For each of these filters (7,0,6), take 16 images while slewing Canopus across a 2x2 pixel diagonal. Exposure values 999, 250, 999 ms, respectively. CanopusCal_2a - (99-154) Slew to put Canopus at center of msi fov. For each of these filters (1,3,4,6), take 16 images while slewing Canopus across a 2x2 pixel diagonal. Exposure values 600, 979, 999, 999 ms, respectively. CanopusCal_2b - (99-166) Slew to put Canopus at center of msi fov. For each of these filters (1,2,3,4,5,6,7,0), take 16 images while slewing Canopus across a 2x2 pixel diagonal. Exposure values are manual, clear= 250ms, all others 999ms. CanopusCal_3a - (99-197) Slew to put Canopus at center of msi fov. Repeat the following for each of these filters (1,2,3,4,5,6,7,0): take 16 images while slewing Canopus across a 2x2 pixel diagonal. Exposure values are manual, clear= 250ms, all others 999ms. CanopusCal_3b - (99-197) Slew to put Canopus about 82 long pixels down, and 188 short pixels to the right of center of boresight (lower right corner of fov). For each filter (1,2,3,4,5,6,7,0) take 16 images while slewing Canopus across a 2x2 pixel diagonal. Exposure values are manual, clear= 250ms, all others 999ms. MSI_Cancal4b - (00-11/0125) This is the normal canopus cal except with Canopus at the following 8 positions. Put Canopus at position 1 (diagram below). A slow scan then moves Canopus across a 2x2 pixel diagonal, while taking 16 images through filter 1. The scan reverses and puts Canopus back to original position. This is repeated for filters 3,4,5,6. Repeat this whole sequence (all 5 filters) at each of the remaining 7 positions. See /eros/00010/msi_cancal4b.gif. _____________________________ | | | . . . | | 5 6 7 | | | | . . | | 4 8 | | | | . . . | | 3 2 1 | |_____________________________| MSI_Cancal4a - (00-12/0040) Put Canopus at center of msi fov. Perform slow scan across 2x2 pixel diagonal while taking 16 images through filter 0. Reposition Canopus to original position. Repeat for all remaining filters (1-7). See /eros/00010/msi_cancal4a.gif. MSI_Cancal5 - (00-38/0610) Put Canopus at center of msi fov. Perform slow scan across 2x2 pixel diagonal while taking 16 images through filter 1, Reposition to original position. Repeat for filters 2,3,4,5,6,7,0, in that order. See /eros/00038/msi_cancal5.gif. MSI_CanCal6 - (00-66/0940) Put Canopus at center of msi fov. Perform slow scan across 2x2 pixel diagonal while taking 16 images through filter 1, Reposition to original position. Repeat for filters 2,3,4,5,6,7, in that order. There was an error in the scan_dur for this one. The imaging goes for 1456 seconds, scanning back and forth across 2x2 pixels only goes for 784 sec (basically through the first 4 filters). MSI_CanPoint - (00-66/1010) Put Canopus at center of msi fov. Take 8 images, spaced 3 sec apart, manual exposures (250, 999, 250, 999, 250, 999, 250, 999ms) for filters (0,4,0,4,0,4,0,4), respectively. MSI_CanCal_7 - (00-99/0746) Put Canopus near center of msi fov. Take 500 filter 2 images (999ms) spaced 12 seconds apart, while performing a slow slew. This is different from previous Canopus cals. The slewing in this one is at the same rate and direction as before (covers equivalent of a 2x2 pixel diagonal in 112 seconds) but it does not reverse direction every 112 seconds. Direction is reversed every 1680 seconds. During that time the slew covers about .277 deg (30 long pixels) in the y direction by .163 deg in z direction (30 short pixels). The slew continues to reverse direction every 1680 seconds for a total of 6002 seconds (which is duration of the imaging). MSI_CanCal_f2 - (00-241/442) Same design as above except with filter 2.
