... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ... For the full set of proposal instructions and requirements, see the FY16 Frontier Fields Lensing Map Call for Proposals....

... Assured of a reliable method of solving the normal equations, we now consider the equations of condition. The observed magnitude m of a star at M air masses with true instrumental magnitude is modelled as ([ 10 ], [ 28 ]) . ... The effective extinction coefficient depends on the effective spectral gradient [ 29 ] of the star, for which we use some color index, affected by half the atmospheric reddening ([ 26 ], [ 10 ]): . ... Thus, for the B band of UBV, we use the (U-V) color. ...

... THE DETAILS . ... proj> : This is just your project number (i.e. a9999) and it is used both for making the executable file name (a9999.exec) and for knowing the name of your .sls set-up files (assumed to be a9999.sls). start_lst(hh:mm) : The is the LST at which your observations will start. ... You tell the program which .sls file to use for a given observation by the target object's priority number -- a priority of 2 selects the "b" set-up file, while all other priorities select the "a" set-up file...
