The DIS:Drift script allows you to take a time series of spectra by moving the object along the slit in the +X direction during an exposure. The range of motion is centered on your starting position, so typically you should begin by putting your object in the center of the slit. ... In detail, the script performs the following sequence: . Slew to the starting position (actually a bit farther because the script allows some time for the telescope to ramp up to speed). ... Take an exposure. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...
