openl1a_hawkeye()

int openl1a_hawkeye

(

filehandle *

file

)

Open the hawkeye L1A file and perform some one-time tasks (as opposed to tasks that are per scan), including: -Get L1A dimensions num_scans, num_bands, num_pixels, num_ccd_temps, num_tlm_blocks (static). Allocate memory for some static arrays based upon these dimensions. -Get L1A group ids e.g. l1aScanLineGrp, l1aEarthViewGrp and it's 8 "band_%d" var ids (static) -Get L1A CCD_temperatures and tlm_delta_time_ms, and call qc_hawkeye_CCD_T to create cleansed versions of these arrays (static). -Get L1A "time_coverage_start" and "time_coverage_end" to derive time_interval (static) etc.

readl1a_hawkeye()

int readl1a_hawkeye	(	filehandle *	file,
		int32_t	oline,
		l1str *	l1rec
	)

Read the specified scan line from the specified L1A file. If this is the first call, call read_cal_hawkeye to read the calibration file, which stores calibration coefficients (for instrument calibration) in static arrays. For each scan, get scan_delta_time_ms and use it to call interp_hawkeye_CCD_T, which sets CCD_temperatures_this_scan[num_ccd_temps]. Then, apply the instrument cal by calling calibrate_hawkeye. Store Lt in l1rec->Lt. Read GEO file.
