## Sky maps for 2018, for mag9 and mag12 # Simulation parameters **Stray light** * ST: conf5 (version of 23/05/2017, should be the last PST) * Sky grid: cartesian, 160x80pts => resolution of 2.25 deg at the equator * Constraints taken into account: *Distances:* - No observation in the atmosphere, i.e. min distance LOS-surface >= 100 km *Angles:* - Sun-LOS (120 deg - default) - Earth-LOS (10 deg from illuminated limb - to reduce the number of points and apply no a priori, although results extremely similar to when angle is 25 deg) * SALSA version: 0.8.1 * Orbit sampling: 1 min * Orbits computed: every 5 **Analysis** - Single day observations: magnitude 9, no constraints on visit duration, one per month: [{'name':'21 January 2018', 'dayofyear':20}, {'name':'21 February 2018', 'dayofyear':51}, {'name':'21 March 2018', 'dayofyear':79}, {'name':'21 April 2018', 'dayofyear':110}, {'name':'21 May 2018', 'dayofyear':140}, {'name':'21 June 2018', 'dayofyear':171}, {'name':'21 July 2018', 'dayofyear':201}, {'name':'19 August 2018', 'dayofyear':230}, {'name':'18 September 2018', 'dayofyear':260}, {'name':'17 October 2018', 'dayofyear':289}, {'name':'16 November 2018', 'dayofyear':309}, {'name':'15 December 2018', 'dayofyear':343},] - (Yearly) sky maps: mag 9 and mag 12 with on-target integration times of a minimum of [19,29,39,49,59,69,79,89,98] minutes per orbit (more or less between 20% and 99% observation efficiency: orbit period is ~98.6 minutes) # Description of ASCII files **Single day** - filename: 6am_700_10_noMoon_conf5-sky_map-0-mag9_onday**DDD**_SAA.dat where **DDD** is replaced by the day number - columns description: ra [rad], dec [rad], obstime [min] **Yearly sky maps** - filename: 6am_700_10_noMoon_conf5_V**mag**_**DD**d_**II**m.dat where: * **mag** is replaced by the mag of the targets * **DD** is replaced by the number of days that the targets must be visible according to science requirements 2.1 and 2.2 (SciReq2.1: V9->50 days , SciReq 2.2 V12->13 days) * **II** is replaced by the on target minimum integration time (in minutes) per orbit - columns descriptions: those files contain a matrix with the observation time in days, when no observation is possible, replaced by NaNs - Ra/dec grids in files ra_grid.dat, dec_grid.dat. - Can be used to directly plot a contour map in Python
