4 xudong 1.23 * This module creates the pipeline Space Weather Active Region Patches (SHARPs).
5 * It is a hard-coded strip-down version of bmap.c.
6 * It takes the Mharp and Bharp series and create the following quantities:
7 *
8 * Series 1: Sharp_CEA
9 * CEA remapped magnetogram, bitmap, continuum, doppler (same size in map coordinate, need manual spec?)
10 * CEA remapped vector field (Br, Bt, Bp) (same as above)
11 * Space weather indices based on vector cutouts (step 2)
12 *
13 * Series 2: Sharp_cutout:
14 * cutouts of magnetogram, bitmap, continuum, doppler (HARP defined, various sizes in CCD pixels)
15 * cutouts of all vector data segments (same as above)

27 * v0.6 Aug 12 2013

29 * v0.8 Feb 12 2014
30 * v0.9 Mar 04 2014
|
31 xudong 1.1 *
32 * Notes:
33 * v0.0
34 * Mharp & Bharp must be fully specified; other input are series names only
35 * All input records need to match, otherwise quit
36 * Mapping parameters depend on keywords of each record only, not necessarily consistent for now
37 * Cutout doesn't work for char segments yet (drms_segment_readslice bug)
38 * SW indices require ephemeris info which is not passed properly as of now
39 * v0.1
40 * Fixed char I/O thanks to Art
41 * SW indices fixed
42 * Added doppler and continuum
|
43 xudong 1.3 * Added other keywords: HEADER (populated by cvs build version), DATE_B
|
44 xudong 1.6 * v0.3
45 * Fixed memory leakage of 0.15G per rec; denoted with "Dec 18"
|
46 xudong 1.7 * v0.4
47 * Took out convert_inplace(). Was causing all the images to be int
|
48 xudong 1.23 * v0.5
49 * Corrected ephemeris keywords, added argument mInfo for setKeys()
|
50 xudong 1.17 * v0.6
51 * Changes in remapping of bitmap and conf_disambig, now near neighbor without anti-aliasing
|
52 xudong 1.23 * v0.7
53 * Added full disk as "b"
54 * Global flag fullDisk is set if "b" is set
55 * Utilize BharpRS and BharpRec all around
56 * Pass mharpRec to set_keys() too in case of full disk
57 * Fixed Bunit (removed from copy_me_keys(), added loops for Bunits in set_keys() here)
58 * Error for CEA still does account for disambiguation yet
59 * v0.8
60 * Added disambig to azimuth during error propagation
61 * Changed usage for disambig: bit 2 (radial acute) for full disk, bit 0 for patch
62 * Fixed disambig cutout for patch: 0 for even, 7 for odd
63 * v0.9
64 * Fixed unit
65 * Check whether in PATCH of FD mode, so the error propagation uses disambiguated azimuth or not
66 *
67 *
68 * Example Calls:
69 * [I] B (full disk disambiguation)
70 * > sharp "mharp=hmi.Mharp_720s[1832][2012.07.12_15:24]" "b=hmi_test.B_720s[2012.07.12_15:24]" "dop=hmi.V_720s[2012.07.12_15:24]" "cont=hmi.Ic_720s[2012.07.12_15:24]" "sharp_cea=su_xudong.sharp_cea_720s" "sharp_cut=su_xudong.sharp_720s"
71 * [II] BHARP (patch disambiguation)
72 * > sharp "mharp=hmi.Mharp_720s[1832][2012.07.12_15:24]" "bharp=hmi.Bharp_720s[1832][2012.07.12_15:24]" "dop=hmi.V_720s[2012.07.12_15:24]" "cont=hmi.Ic_720s[2012.07.12_15:24]" "sharp_cea=su_xudong.sharp_cea_720s" "sharp_cut=su_xudong.sharp_720s"
